If possible, can someone tell me how to make it to where the first 2 characters of the password generated is only numbers? No symbols or letters? Thanks

There are many ways, here's one:

 

$password = rand(0,9) . rand(0,9) . $password_22_chars_long;

oops, I meant to say only letters for the first 2 characters of the password.. no numbers or symbols

 

also I put that in and it only writes a 2 digit number to my text file

This is one way, regex might not be right, un-tested.

if(!preg_match('~^[A-Za-z]{2}~',$password)) {
$hold = $characters[rand(0,51)];
$hold .= $characters[rand(0,51)];
$password = preg_replace('~^(.){2}~',$hold,$password);
}

This will generate the passwords into an array for you as you specify. Use implode() to convert to a string to write into the file:

 

<?php

function generatePasswords($count, $length)
{
    $passwordAry = array();
    $characters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ123456789$*%><)(][';
    for($i=0; $i<$count; $i++)
    {
        $passwordAry[$i]  = $characters[rand(0, 51)] . $characters[rand(0, 51)];
        $passwordAry[$i] .= substr(str_shuffle($characters), 0, $length-2);
    }
    return $passwordAry;
}

$passwords = generatePasswords($password_count, $password_length);

?>
