使用正则表达式PHP获取两个定界符之间的所有字符串（子字符串）

Question

Can anybody help me with a function in php using regex to return all founded sub strings between two delimiters.

expmple :

<p class="mn"><a href="123517/2882"> Hi all 5 </a>
<p class="mn"><a href="123518/2662"> Hi all 6 </a>
<p class="mn"><a href="123519/2552"> Hi all 55 </a>
<p class="mn"><a href="1235100/7722"> Hi all 15</a>

I need to get all substrings between <p class="mn"><a href=" and "> using regex php function.

I tried some methods here but I can not handle regex syntax rightly, so I need a help with regex syntax and how to use it.

thanks

In the specific sense, try

preg_match_all('@<p class="mn"><a href="(.+?)">@', $str, $m);

In the general sense, parse the HTML with a library and use XPath .
