Random Password generator with PHP

Sometimes we need to create a random password generator in our web application. This random password will be given to the user. This is a nice idea to force users to use a secure password. This is a working random password generation function for PHP. Just include this function anywhere in your code and then use it.

In this code, I have removed the l and 1 because it can create confusion in passwords. It means, generated password will not contain 1 and l both. If you want to use, you can add it in the code. This code will generate a random password with mixture of characters, numbers and special characters.

You can also see the demo of this password generator function from the link below.

Random Password generator with PHP

<?php

function createRandomPassword()
{
$chars = "[email protected]#$%&*()?~abcdefghijkmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ023456789";
$len=strlen($chars);
srand((double)microtime()*1000000);
$i = 0;
$pass = '' ;
while ($i <= 10)
{
$num = rand(0,$len);
$tmp = substr($chars, $num, 1);
$pass = $pass . $tmp;
$i++;
}
return $pass;
}

$newpassword = createRandomPassword();
echo "Your random password is: $newpassword";
?>

You can also improve this function to make it better. If you have better code, you can share it with us and I will be happy to share that code with our readers along with giving you full credits for that code.
