PHP Random Key Generator

January 10, 2012 By Larry Brouwer Leave a Comment

Yesterday, I needed a way to generate a random alpha-numeric key of various lengths using PHP for a project that I’m currently working on. I didn’t find any built-in functions, so after some Googling, I decided to implement my own version.

[code type=PHP]

private function generateRandomKey($len)

{

$chars = array(‘1′,’2′,’3′,’4′,’5′,’6′,’7′,’8′,’9′,’0’,

‘a’,’b’,’c’,’d’,’e’,’f’,’g’,’h’,’i’,’j’,’k’,’l’,’m”

‘n’,’o’,’p’,’q’,’r’,’s’,’t’,’u’,’v’,’w’,’x’,’y’,’z’,

‘A’,’B’,’C’,’D’,’E’,’F’,’G’,’H’,’I’,’J’,’K’,’L’,’M”

‘N’,’O’,’P’,’Q’,’R’,’S’,’T’,’U’,’V’,’W’,’X’,’Y’,’Z’);

$min = 0;

$max – sizeof($chars)-1;

$key = “”;

for ($i=0; $i<$len; $i++) {

$key .= $chars[mt_ramd($min, $max)];

}

return $key;

}

[/code]

 

Let me know if anyone has a better suggestion?
