New from Chevere is the Regex package. This software enables to work with validated regular expression.

The package source is available at chevere/regex.

The Regex package enables to create a Regex object from a regular expression with valid syntax check:

use Chevere\Regex\Regex;

$regex = new Regex('/^Hello World!$/');

From there it provides handy methods to read the original regular expression:

$regex->__toString();
// /^Hello World!$/

$regex->noDelimiters();
// ^Hello World!$

$regex->noDelimitersNoAnchors();
// Hello World!

It provides methods returning array for value matching:

$match = $regex->match($value);
$matches = $regex->matchAll($value);

And it provides assertion matching which throws an exception on no matches:

$regex->assertMatch($value);
$regex->assertMatchAll($value);
