How to generate random password with PHP?

Question

Or is there a software to auto generate random passwords?

Answer 1

I want to play the game. The simplest way would be to do:

function rand_passwd( $length = 8, $chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789' ) {
    return substr( str_shuffle( $chars ), 0, $length );
}

This is pretty much just a modification of the first answer. Specify the characters you want in the second parameters and the length of the password in the first.
