lutzissler / func.multiple_strftime.php

Last active August 15, 2021 20:17

Works like strftime() but allows for multiple occurences of the formatting tokens, just like sprintf(). Also, add capability for 'O' (uppercase letter “oh”) which creates an ordinal day suffix, 'K' for the shorted 24 hour format possible ('8' instead of '08:00', '12' for '12:00', '12:15' for '12:15'), 'L' for the shortest 12 hour format possible…

	function multiple_strftime($format) {
	if (func_num_args() < 2) {
	return $format;
	}
	$args = func_get_args();
	return strftime(preg_replace_callback('/%(\d)\$(.)/', function ($match) use ($args) {
	if (isset($args[$match[1]])) {
	if ($match[2] == 'O') {
	// Ordinal day suffix
	return date('S', $args[$match[1]]);
