Create Random Alphanumeric Password in PHP

Posted by admin in PHP on November 12th, 2009

We can use this simple password generation function to create random passwords. The maximum limit of generated password is 36 characters.

<?php
	function gen_password($size = 8) {
		$size = $size > 36 ? 30 : $size;
		$pool = array_merge(range(0, 9), range('A', 'Z'));
		$rand_keys = array_rand($pool, $size);
 
		$password = '';
 
		foreach ($rand_keys as $key) {
			$password .= $pool[$key];
		}
 
		return $password;
	}
 
	$password = gen_password(10);
?>

We can use it like this.

<?php
	$password = gen_password(10);
?>
