A random password generator. The script can generate passwords of varying complexity. You can specify the maximum and minimum length of the password and the characters that are to be included in the password.
| <?php
function random_string($minlength = 6, $maxlength = 6, $uselower = true, $useupper = false, $usenumbers = true, $usespecial = false){
$charset = '';
if ($useupper) $charset .= "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
if ($usenumbers) $charset .= "1234567890";
if ($usespecial) $charset .= "~@#$%^*()_+-={}|][";
if (empty($charset) || $uselower) $charset .= "abcdefghijklmnopqrstuvwxyz";
$length = ($minlength > $maxlength) ? mt_rand ($maxlength, $minlength) : mt_rand ($minlength, $maxlength);
$charsetlength = strlen($charset) - 1;
for ($i=0; $i<$length; $i++) {
$str .= $charset[mt_rand(0, $charsetlength)];
}
return $str;
}
echo 'SIMPLEST : ' . random_string(5, 5, false, false) . "<br>\n";
echo 'SIMPLE : ' . random_string(5, 5, false, true, false) . "<br>\n";
echo 'MEDIUM : ' . random_string() . "<br>\n";
echo 'HARD : ' . random_string(5, 10, true, true, false) . "<br>\n";
echo 'HARDER : ' . random_string(5, 10, true, true) . "<br>\n";
echo 'HARDEST : ' . random_string(5, 10, true, true, true, true) . "<br>\n";
