php 中的组替换
group replacement in php
我需要以这种方式修改 links(全局)
http://www.domain.de/specific-folder/{数据}/#link
对此:
http://{data}.domain.de/#link
{data} = changing folder name
我试过了,但我不知道如何在 php (preg_replace)?
中处理组替换
$re = "/\/specific-folder\/*([0-9,a-z,A-Z,-]*)(.*)/";
$str = "http://www.domain.de/specific-folder/data/#link";
$subst = // works, but i can't get rid of the original search string (?)
非常感谢任何提示!
您可以使用:
$str = preg_replace('~(http://)www\.(domain\.de)/specific-folder/([^/]+)~', '', $str);
^[^.]*\.([^\/]*)\/.*?\/({.*?})\/(#.*)$
尝试 this.See 演示。

$re = "/^[^.]*\.([^\/]*)\/.*?\/({.*?})\/(#.*)$/m";
$str = "http://www.domain.de/specific-folder/{data}/#link";
$subst = "http://./";
$result = preg_replace($re, $subst, $str);
