Random Password Generator PHP Script - IceCaves.net Webmasters

Random Password Generator PHP ScriptWritten by: Haily, Icy | Easily create a script that can generate a random string of text that may be used as a password or anything else.

This article will show you how to create a random password generator script. Please read on, and comment below if you have
any questions at all.

The setup for this is fairly simple. The function that generates the password goes through the $characters variable and selects a random character to generate the password until the length of the desired password:

Code:

<?php

function randomPassword ($length = 7){

// define possible characters
$characters = "abcdefghijklmnopqrstuvwxyz1234567890!@#$%^&*";

// using the for loop to add random characters to $password until $length is reached
for ($y=1; $y<=$length; $y++){

//randomly selecting characters and building the password with them
$randompw = rand() %strlen($characters);
$temp = substr($characters, $randompw,1);
$password = $password . $temp;

}

return $password;

}

echo "Generated Password: " .randomPassword();

?>

You can use this function to easily generate random passwords. Instead of calling up the function simply as randomPassword() to call up a 7-character long password, you can insert a number as a parameter to generate a password of any length. For example, randomPassword(5) or randomPassword(10) for various password lengths. Try it out for yourself. Enjoy!

	Great article Haily & Icy! I've always wanted to know how to make this, never knew how easy it was. Not to mention it is customisable too. It is so simple!
