google app engine php code
<p>I have deployed my application on google app engine .The input entered by the user on the form invokes the email.php file(mentioned below in the code) to send out an email  .
However, when I deploy this ,when the php file(email.php) is being  called the script is not executed and the the script is being displayed in the localhost.
I have read the other posts on configuring the app.yaml file it does not help.
Let me know what has to be done.</p>

<p>app.yml</p>

<pre><code>application: shop_app  
version: alpha-001  
runtime: php55  
api_version: 1  
handlers:  
-url: /email.php  
script: assets/email.php      
</code></pre>

<p>.php file</p>

<pre><code>&lt;?php  
  $name = $_POST['fname'];  
  $lname = $_POST['lname'];  
  $email_address = $_POST['email'];  
  $phone = $_POST['phone'];  
  $message = $_POST['message'];  

  // Create the email and send the message  
  $to = 'vikraj@gmail.com'; 
  $email_subject = "Website Contact Form:  $name";  
  $email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nFirst Name: $name\n\nLast Name:$lname\n\nEmail: $email_address\n\nPhone: $phone\n\nMessage:\n\n$message";               
  $headers = "From: userjoe@gmail.com\n"; // This is the email address the generated message will be from. We recommend using something like noreply@yourdomain.com.
   $headers .= "Reply-To: $email_address";    
  mail($to,$email_subject,$email_body,$headers);  

  /* Redirect browser */  
  header("Location: index.html");  
?&gt;
</code></pre>
