A better way?

[rarebit]

Hi, is there a better way to find if a key 'partially' exists in an array. When I say better I mean a built in function? Heres what i've scraped together:

$key = -1;
foreach($_POST as $k => $v)
{
	if(strcmp("SUB_", substr($k, 0, 4))==0)
	{
		$key = $k;
		break;
	}
}

 

It comes from a submit button and probably not allowed to use an array of buttons...

 

Cheers!
