[SOLVED] Search for regex in text.

[peeps]

I have googled many different things, but I cannot grasp how to pull the text that matches the regular expression from text I want to look in. Maybe I just don't know how to word my question. I have tried preg_grep and am not sure that even does what I want to do. What I am doing now is:

$tosearch = explode(" ",$sometext);

foreach($tosearch as $value){
  	if(eregi('[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}',$value)){
	$mac = $value;
	}
}

that works, but what I want to do is:

$mac = preg_grep('[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}', $sometext); //$sometext not being an array

The above gives an error complaining about not being an array.

Thanks.

preg_match('[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}-[A-Z0-9]{2}', $sometext,$mac);
print_r($mac);

Thanks, that works just like i wanted.
