求一正则,替换img标签的src属性
如题,我的$data['content']里有很多内容,其中也有img标签:
求1正则,替换img标签的src属性


我想得到把src属性里的/Uploads/去掉,其他的保存不变。正则一直不怎么会,求大神告诉我怎么过滤,谢谢

------解决思路----------------------

<br />preg_replace('`src="/Uploads/([^"]+?)"`','src="$1"',$data['content']);<br />

------解决思路----------------------
^ 除了 “ 都匹配,+ 至少一个,? 非贪婪(尽可能少的)匹配

就是匹配到后面正常的链接(相当于用 ” 来做匹配的结束),用$1表示捕获到的内容
------解决思路----------------------
 [^"] 不是 " 的所有字符 
+? 非贪婪匹配

用在这里多余了
