中的[img src=xxxx.jpg]
改成<img src="./upload/xxxx.jpg" style="max-width:90%" height="100px" alt="求php正则表达式方法" >

<code class="lang-php">$str = '[img src=sorqin_2014523174838.jpg] 2013 asdfdfdghhhhhhh[img src=sorqin_2014523174838.jpg]sdgfdgdfghdhgfhjfjghjg'; $str = preg_replace('/\[img\s+src=(.*?)\]/is', '<img src="./upload/%241" style="max-width:90%" height="100px" alt="求php正则表达式方法" >', $str); echo $str; </code>
不太熟悉PHP的正则,如果是在js里的话,可以这样
<code>var str = '[img src=sorqin_2014523174838.jpg] 2013 asdfdfdghhhhhhh[img src=sorqin_2014523174838.jpg]sdgfdgdfghdhgfhjfjghjg'; str.replace(/\[/g, '').replace(/(src=)(.+?\.jpg)/g, '$1"./upload/$2" width="100px" height="100px"'); </code>
可以把上面的代码贴到浏览器的控制台里试一下
PHP中的话,使用PHP里相应的replace
方法应该就可以了
$str = '[img src=sorqin_2014523174838.jpg] 2013 asdfdfdghhhhhhh[img src=sorqin_2014523174838.jpg]sdgfdgdfghdhgfhjfjghjg';
$hack = array('/\[/', '/\]/', '/(src=)(.+?\.jpg)/');
$replace = array('', '$1"./upload/$2" width="100px" height="100px"');
preg_replace($hack, $replace, $str);
