While we creating random password we often use time() function with md5() to get unique
hashes. What happens if the functions processed exact time?. Below i've listed a function
which creates random unique password hashes.
This function will use mt_rand to get random number along with the tocken then it is passed
in md5() to create unique password hashes.
//$l= lenth of the created password
function unique_id($l=3) {
$token="]#S$.";
$token.=uniqid(mt_rand(), true);
return substr(md5($token), 0, $l);
}
echo unique_id(7);
