file_get_contents generating 500 error

Question

I have a file php that gives a file_get_contents in archives json.
PHP can see the files because the file_exists works just right.
But if I give file_get_contents in the same file as the file_exists PHP returns me:

error 500 (internal server).

<?php 
date_default_timezone_set('America/Sao_Paulo'); $jogosF = 1; $datadehj = date("Y-m-d"); $horaAgora = date("H:i"); $array = array(); $tempo = (10 * 60); while(file_exists("../../../txts/bkpjogosF". $jogosF .".json")) {
$conteudo = file_get_contents("../../../txts/bkpjogosF". $jogosF .".json");
$conteudo = json_decode($conteudo);

Note: The folder on the server has chmod -R 777 file, ie full permission. I have tried using the fopen, and made the same mistake.
On LOCALHOST with XAMPP it works.

file_get_contents is a function that depending on how you use may represent a security breach, so the use of it is activated by php.ini

If you use it without enabling it in php.ini it will return this error 500.

To enable change:

allow_url_fopen = 1

But it is HIGHLY recommended to use the CURL instead of this function.

function get_content($URL){
    $ch = curl_init();
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_URL, $URL);
      $data = curl_exec($ch);
      curl_close($ch);
      return $data;
}

Use: echo get_content('http://example.com');
