<?php $emails = array("tcely", "cely@iqnection.com", "cely@tenable.com", "Chris.Ely@gmail.com", "tcely@users.noreply.github.com"); foreach ($emails as $k => $email) { $md5 = md5( strtolower( trim( $email ) ) ); $sha1 = sha1( strtolower( trim( $email ) ) ); printf('email: %-30s'."=>\n", $email); printf("\t".'https://identicons.github.com/%s.png'."\n", $md5); printf("\t".'https://identicons.github.com/%s.png'."\n", $sha1); }

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).
