具体问题：

正文中有多个这样的标签，如下

<img src="/static/imghwm/default1.png"  data-src="/case/clxy/page/files/newspic/20090928084704364888.jpg"  class="lazy"     style="max-width:90%"  style="max-width:90%" alt=" "  border="0" />

我要将其中src中的路径去掉开头的 "/case/clxy/page/"
是要正文中的所有的img标签都是要替换的。

实现方法：

这个还要写正则！ 直接用DW 就可以批量替换了!

帮你写了一个

$url ='<img src="/static/imghwm/default1.png"  data-src="/case/clxy/page/files/newspic/20090928084704364888.jpg"  class="lazy"     style="max-width:90%"  style="max-width:90%" alt=" "  border="0" />';
$ok=preg_replace('/()/i',"\${1}\${3}",$url);
echo $ok;

替换后的结果为

<img src="/static/imghwm/default1.png"  data-src="/files/newspic/20090928084704364888.jpg"  class="lazy"     style="max-width:90%"  style="max-width:90%" alt=" "  border="0" />
