My favorite new style of printf

May 20th, 2006 • Related • Filed Under

I just discovered vsprintf(), which accepts a formatting string and an array of arguments:


// logging function that accepts printf-style formatting
// it prints a time stamp, the string, and a new line
function logf() {
	$date = date(DATE_RSS);
	$args = func_get_args();
	$format = array_shift($args);

	return print "$date: " . vsprintf($format, $args) . "\n";
}

Just sharing.
