VerbalExpressions is a PHP library that helps to construct hard regular expressions.

The project supports Composer so you have to install Composer first, before project setup.
$ composer require verbalexpressions/php-verbal-expressions:dev-master
Examples
<?php // some tests require './vendor/autoload.php'; use VerbalExpressions\PHPVerbalExpressions\VerbalExpressions; $regex = new VerbalExpressions(); $regex->startOfLine() ->then("http") ->maybe("s") ->then("://") ->maybe("www.") ->anythingBut(" ") ->endOfLine(); if ($regex->test("http://github.com")) { echo "valid url". '<br>'; } else { echo "invalid url". '<br>'; } if (preg_match($regex, 'http://github.com')) { echo 'valid url'; } else { echo 'invalid url'; } echo "<pre>". $regex->getRegex() ."</pre>"; echo $regex->clean(array("modifiers" => "m", "replaceLimit" => 4)) ->find(' ') ->replace("This is a small test http://somesite.com and some more text.", "-");
