1 2 3 4 5 6 7 8 9 10 11 12 13 | <?php function udate( $format = 'u' , $utimestamp = null) { if ( is_null ( $utimestamp )) $utimestamp = microtime(true); $timestamp = floor ( $utimestamp ); $milliseconds = round (( $utimestamp - $timestamp ) * 1000000); return date (preg_replace( '`(?<!\\\\)u`' , $milliseconds , $format ), $timestamp ); } echo udate( 'Y-m-d H:i:s.u' ); ?> |
