Randomly generated number/password

readme

What if I need to use a randomly generated password in multiple locations within PHP? I have two instances of $password with in PHP. One used as part of an attachment name that will get emailed and the other inserted inline of HTML that is with in my PHP. This results in a totally different password being generated. Is there a way I can ’save’ the initially generated password into another variable that I may use throughout? Total novice here…please enlighten me. Thanks!

<?php
$pdfAttachment = file_get_contents('php://input');

$fp = fopen( 'app_complete.pdf', 'wb' );
fwrite( $fp, $pdfAttachment );
fclose( $fp );

$password = rand(10000, 99999);
$pdfname = $password.'.pdf';


$to = 'xxxxx@xxxxx.com';
$subject = 'Test email with attachment';
$random_hash = md5(date('r', time()));

$headers = "From: webmaster@example.com\r\nReply-To: webmaster@example.com";

$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";

$attachment = chunk_split(base64_encode($pdfAttachment));

ob_start();

?>
--PHP-mixed-<?php echo $random_hash; ?> 
Content-Type: multipart/alternative; boundary="PHP-alt-<?php echo $random_hash; ?>"

--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

Hello World!!!
This is simple text email message.

--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

<h2>Hello World!</h2>
<p>This is something with <b>HTML</b> formatting.</p>

--PHP-alt-<?php echo $random_hash; ?>--

--PHP-mixed-<?php echo $random_hash; ?> 
Content-Type: application/pdf; name="<?php echo $pdfname; ?>" 
Content-Transfer-Encoding: base64 
Content-Disposition: attachment 

<?php echo $attachment; ?>
--PHP-mixed-<?php echo $random_hash; ?>--

2nd use of $password in mail reply

<?php
$message = ob_get_clean();
$mail_sent = @mail( $to, $subject, $message, $headers );

echo $mail_sent ? "<body style='background-color: #F1DFB7; font-family:Arial,
Helvetica, sans-serif; color:#760813;'>
<div align='center'>Thank you for your submition. <br />
  <br />
  Please write down your application ticket number for future reference: 
  <br />
  <br />
  <p style='font-size: 24px; color:#968a2a; font-weight:bold;'>$password</p>
  <br />
  <p style='font-size: 10px; color:#968a2a; font-weight:bold;'><a href='javascript: history.go(-2)'>BACK TO PREVIOUS PAGE</a></p>
</div>
</body>" : "Mail failed";
?>

You want sessions

You can store the data in a $_SESSION super global and access it on any other page that you start the sessions on (as long as you use the same session ID and your session isn't expired). You will need to start the session before any data is sent to the browser and call session start on every page you want to use sessions (unless sessions are auto-started in php.ini)

i.e.
index.php

<?php
  session_start();
  $_SESSION['pass'] = 'abc';
  header('Location: index2.php');

index2.php

<?php
  session_start();
  echo 'Your password is: '.$_SESSION['pass'];

Sessions are much like Cookies, except they reside on the server instead of the client.
