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

<?php $regularExpression = $_POST['regularExpression']; $textContent = $_POST['textContent']; if (preg_match_all ($regularExpression, $textContent, $result)){ if ($result[2]){ $regexResult = $result[2]; echo json_encode($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.
