Why is my php amazon elastic transcoder working from root but not from a browser?

Question

I am trying to execute a job that will transcode a video file. I have a php file:

<?php
require 'vendor/autoload.php';

use Aws\ElasticTranscoder\ElasticTranscoderClient;

// Create a service locator using a configuration file
$client = ElasticTranscoderClient::factory(array(
        'key'    => 'my key',
        'secret' => 'my secret',
        'region' => 'us-west-2',
));

$result = $client->createJob(array(
        'PipelineId' => 'my pipeline id',
        'Input' => array(
                'Key' => 'video.mp4',
                'FrameRate' => 'auto',
                'Resolution' => 'auto',
                'AspectRatio' => 'auto', 
                'Interlaced' => 'auto',
                'Container' => 'auto',
        ),
        'Output' => array(
                'Key' => 'output.mp4',
                'ThumbnailPattern' => 'thumb{count}.jpg',
                'Rotate' => 'auto',
                'PresetId' => '1351620000001-000010',
        ),
));

?>

and I call this script like transcoder.php

The thing is that if I call this from my root from VPS like php transcoder.php it works just fine, but if I try to call it from my browser (safari, chrome, firefox) I get a

Why does it work from root and but not from browser? I need to access it from the browser.

Answer 1

Try changing the settings from php.ini regarding curl and exec, that`s why you dont have permission to access the script from the browser, but works from root console.
