(10) PHP regular expression learning ---- making test tools

1. Reason:

Make a PHP testing tool so that you can directly test the regular rules. This tool can be developed in the future.

2. Code:

index.php

<meta charset="UTF-8">
<link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
<script src="//cdn.bootcss.com/jquery/1.11.3/jquery.min.js"></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>



<div style="padding: 30px 300px 10px;" id="content">
    <h2 id="正则表达式测试">正则表达式测试</h2>

        echo json_encode($regexResult);
    }

The above has introduced (10) PHP regular expression learning-the production of test tools, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
