Nice little function that will generate a completely random password.
Code: Select all
<?php
/**
* The letter l (lowercase L) and the number 1
* have been removed, as they can be mistaken
* for each other.
*/
function createRandomPassword() {
$chars = "abcdefghijkmnopqrstuvwxyz023456789";
srand((double)microtime()*1000000);
$i = 0;
$pass = '' ;
while ($i <= 7) {
$num = rand() % 33;
$tmp = substr($chars, $num, 1);
$pass = $pass . $tmp;
$i++;
}
return $pass;
}
// Usage
$password = createRandomPassword();
echo "Your random password is: $password";
?>
