    You have one too many %s in the sprintf.
    The correct line should be:
    
    "%s://%s",

    printf is one of those commands I never really understood why they exist in the first place.... as if string addition is so magically hard or that it's somehow worth running a parser under a parser under an interpreter.

    Which is why I'd have scrapped that and simply done:
    
    function httpcheckif(){
    	return (
    		isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http'
    	) . '://' . $_SERVER['SERVER_NAME'];
    }
    
    Code (markup):
    Even in C all "printf" type commands are is a legacy of the fact that the early compilers were all single-pass trash... that it even exists in modern languages like PHP is more a monument to stupidity than it is functionality.
