正则表达式用于隔离字符串的特定部分

Question

我努力寻找正确的正则表达式来回归：

'industry =[[Banking]], [[Financial services]] |products = [[Investment Banking]]'

来自以下内容：

<?php
$x =  '[[Basel]] |key_people = [[Axel A. Weber]] (Chairman){{br}}[[Sergio  
Ermotti]] (CEO) {{br}} |area_served = Worldwide |industry =[[Banking]],   
[[Financial services]] |products = [[Investment Banking]]';
';
?>

Answer 1

使用preg_match来加盖|分隔文字的最后两部分。

preg_match('~(?<=\|)[^|]*\|[^|]*$~', $str);
