Three Missing String Functions

This is an archive post, any discussion should take place here http://betterphp.co.uk/board/viewtopic.php?f=5&t=8

These are three functions from my standard php library. they tend to be pretty useful as I get sick of having to constantly look up the order of parameters for strpos

function str_starts_with($needle, $haystack){
	$needle_len = strlen($needle);
	
	return ($needle_len <= strlen($haystack) && substr($haystack, 0, $needle_len) === $needle);
}

function str_ends_with($needle, $haystack){
	$needle_len = strlen($needle);
	
	return ($needle_len <= strlen($haystack) && substr($haystack, -$needle_len) === $needle);
}

function str_contains($needle, $haystack){
	return (strpos($haystack, $needle) !== false);
}

fairly self explanatory really.
