I was super bored. So I made this.

gistfile1.aw

<?php
abstract class Type {

	protected $type;

	public abstract function isValid();

	public function getType() {
	
		return $this->type;
	
	}

}

class RegExp extends Type {

	const REGEX_PATTERN_VALIDATE = '/^(?:([^[:alpha:]\\\\{<\[\(])(.+)(?:\1))|(?:{(.+)})|(?:<(.+)>)|(?:\[(.+)\])|(?:\((.+)\))[gimsxu]*$/';
	
	protected $type = 'regexp';
	
	protected $regexp;
	
	public function __construct($regexp) {
	
		$this->regexp = $regexp;
	
	}
	
	public function isValid() {
	
		return preg_match(self::REGEX_PATTERN_VALIDATE, $this->regexp);
	
	}
	
	public function getRegExp() {
	
		if($this->isValid() === true) {
		
			return $this->regexp;
		
		}
	
		return null;
	
	}
	
	public function match($string) {
	
		preg_match($this->regexp, $string, $matches);
	
		return $matches;
	
	}
	
	public function matchAll($string) {
	
		preg_match_all($this->regexp, $string, $matches);
	
		return $matches;
	
	}

	public function test($string) {
	
		$matches = count($this->match($string));
		
		if($matches > 0) {
		
			return true;
		
		}
		
		return false;
	
	}
	
	public function split($string, $limit = -1, $flags = 0) {
	
		return preg_split($this->regexp, $string, $limit, $flags);
	
	}

	public function replace($string, $replace, $limit = -1) {
	
		return preg_replace($this->regexp, $replace, $string, $limit);
	
	}

	public function __toString() {
	
		return $this->getRegExp();
	
	}

}


$regex = new RegExp('/(hello)/');


var_dump(

	$regex->test('hello Robin')

);
?>
