Question

I was trying to run a simple PHP script on Amazon EC2.
As i got blank screen on the browser, started putting some garbage syntax or echo in between steps. Then i figured out that script was failing without any error.

How to disable silent failure?

<?php

putenv('HOME=/root');
echo 'after env'; //displayed on browser
require_once('/home/ec2-user/AWSSDKforPHP/sdk.class.php'); 
//i believe this require step was failed 
echo 'after require'; // not displayed on browser
$ec2 = new AmazonEC2();
$response = $ec2->describe_availability_zones();
print_r($response);
echo 'hello';

?>

It can depend on your php.ini settings, error display or error reporting might be off.

Add this to the top of your script:

ini_set('display_errors', 1);
error_reporting(E_ALL);
