Question

I want to generate a random password that has the following pattern:

Capital, small, number, dash, capital, small, number, special charachter.

Example:

Ab1-Cd2$

I have put all the special characters in an array that I randomly pick, so I have that part figured out. But I have no clue of how to do the other part. Any suggestion?

Answer 1

this is not the best way, but this will work

<?php

    $capital    = range ('A','Z');
    $small      = range ('a','z');
    $number     = range ('0','9');
    $special    = array ("#","$","@");

    $password   =   $capital[array_rand($capital)] . 
                    $small[array_rand($small)] . 
                    $number[array_rand($number)] . 
                    "-" . 
                    $capital[array_rand($capital)] . 
                    $small[array_rand($small)] . 
                    $number[array_rand($number)] . 
                    $special[array_rand($special)];

    print $password;

You can read about the functions i used here

array_rand

range

Will produce results like:

Tg8-Im1$
Yj3-Xl3@
Cr1-Lv1@

which i guess is your requirement

Please let me know if you want any more help on this.
