A simple example of PHP regular matching and substitution

A simple example of PHP regular matching and substitution, with a match to get an example of a rent-plus font and a matching replacement hyperlink.

1. Find the contents of matching <b> and </b> tags:

<?php$str = "Name: <b>PHP</b> <br> Title: <b>programming language</b>";p Reg_match_ All ("/<b> (. *) <\/b>/u", $str, $arr);p rint_r ($arr [0]);? >

The execution results are as follows:

Array (    [0] = <b>PHP</b>    [1] = <b>programming language</b>)
