PHP - Blog Server Help

Following a tutorial on udemy, i tried to learn the very basics of mvc structure. I built the same project on my local server and it worked without giving me any error. but when i tried it on live server. its not working as it should. not showing any error. I tried to figure out the problem and found that for every page loading, it stops at the same line in my main.php file.

<?php require($view); ?>

starting from the above line. it stops. i came here to share my problem but i am unable to upload my files here. if there is a way to upload and share my files, please guide. zip file size of the whole project is 31.6 kb

if(missingInformation) {echo(0);}
else {
   session_start();
   $_SESSION['_xfr']=$_POST;
   exec('/usr/bin/php -q /path/to/send_fax.php '.session_id().' >/dev/null &');
   echo(1);
}

session_id($argv[1]);//Set by parent
session_start();
$data=$_SESSION['_xfr'];

$doc_list=null;
foreach ($data['documents'] AS $doc)
{
    if(ctype_alnum($doc['id']))
    {
        $file='/some/tmp/directory/'.$doc['id'];
        if(!file_exists($file))
        {
            $url='http://machine.WebServer.com/index.php?task=displayDocument&id='.$doc['id'].'&x='.hash('sha256','displayDocument'.$doc['id'].'secretCodeWhichOnlyWebServerAndFaxServerKnow');
            $cmd='wget -O '.$file.' '.escapeshellarg($url);
            exec($cmd);
        }    
        $doc_list.=' '.$file;
    }
    exit('invalid document');
}

//Send the fax...

//Send another CURL request to the WebServer similar to the wget giving the fax status.
exit;
