PHP Password Generator

Here is a very simple function that will generate a string of random characters, ideal if you want to create a password for a new user.

function generatePassword($length=10)


{


 $pass = '';


 $parts = array_merge(range(0, 9),range('a', 'z'),range('A', 'Z')); 


 for ($i=0; strlen($pass) <= $length; $i++) {


  $pass .= $parts[array_rand($parts)];


 }


 return $pass;


}

Use the function like this.

echo generatePassword();

To create a longer password string just pass a parameter with the function.

echo generatePassword(5);
