You can use one variable to check execution $time as follow:
<?php
$time = -microtime(true);
$hash = 0;
for ($i=0; $i < rand(1000,4000); ++$i) {
$hash ^=
md5(substr(str_shuffle("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"),
0, rand(1,10)));
}
$time += microtime(true);
echo "Hash: $hash iterations:$i time: ",sprintf('%f', $time),PHP_EOL;
?>
