Submit form with password generator - need help

[nutt318]

Well I want a simple form on my site that a user can input their email address and then hit submit. Once they hit the submit button I also want it to create a generic password and write the email address and generic password to a text file on my site.

 

Anyways I have the following code, It generates the password but im not sure how to post the information to a text file including the generic password.

 

<?php



/**

* The letter l (lowercase L) and the number 1

* have been removed, as they can be mistaken

* for each other.

*/



function createRandomPassword() {



    $chars = "abcdefghijkmnopqrstuvwxyz023456789";

    srand((double)microtime()*1000000);

    $i = 0;

    $pass = '' ;



    while ($i <= 7) {

        $num = rand() % 33;

        $tmp = substr($chars, $num, 1);

        $pass = $pass . $tmp;

        $i++;

    }



    return $pass;



}



// Usage

$password = createRandomPassword();

echo "Your random password is: $password";



?>

<form action="signup2.php" method="post" name="signup">

    <p>E-mail Address:  
      <input name="email" type="text" />
  	  
      <input name="submit" value="Sign Up" class="submit-button" type="submit" />
    </p>
</form>

 

Thanks for your help.
