<?php foreach ( array( 1, 2, 3 ) as $v ) { $hash = strtoupper( substr( md5( $v ), 0, 16 ) ); echo substr( $hash, 0, 4 ) . '-' . substr( $hash, 4, 4 ) . '-'. substr( $hash, 8, 4 ) . "\n"; }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
