PHP - Mysterious Error in Upload script - php

Question

i'm trying to upload a file to vshare.io trough their api. They're offering a php script to do so:
<?php
if(!function_exists('curl_init')) {
die('CURL functions are not available. Debian: apt-get install php5-curl');
}
$file_path = ''; // Example: $file_path = '/home/files/file.exe';
$token = ''; // You can get your TOKEN from the following page http://vshare.io/api.html
$post = array(
'token' => $token,
'filesize' => filesize($file_path),
'Filedata' => '#' . $file_path
);
// init
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://upload.vshare.io/upload_api.php');
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Expect: "));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$result = curl_exec($ch);
curl_close($ch);
$output = json_decode($result, TRUE);
if(isset($output['upload'], $output['video'], $output['fileid']) && strlen($output['fileid']) == 7 && $output['upload'] == 1) {
if($output['video'] == '1') {
$file_type = 'video';
} elseif($output['video'] == '0') {
$file_type = 'file';
}
echo 'File Type: ' . $file_type . ' | File Link: http://vshare.io/d/' . $output['fileid'];
} else {
echo 'Error: ' . $output['msg'];
}
?>
i inserted my token and the correct filepath in Ubuntu, however when launching the script it will run for about 1 minute and then it will print "Error:" (last line of the script say to do so). No files are uploaded to my account
Any hint?

Answer 1

There could be 2 reasons. First is your user-agent, you have not set it. The most site today restricted BOT so you should set it for your CURL:
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17');
The second reason is that the CURL process time out so you got nothing nor any message.
Try this
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,0);
curl_setopt($ch, CURLOPT_TIMEOUT, 400);
