Opening gzipped json for all categories in MELI (MLA)

PHP-All-Categories.php

<?php
ini_set("memory_limit","500M"); //less should be enough, but I came to this number checking
$options = array('http'=>array('header'=>"Accept-Encoding: gzip\r\n")); 
$context = stream_context_create($options); 

$results = file_get_contents('compress.zlib://https://api.mercadolibre.com/sites/MLA/categories/all', 0, $context); 
$results = json_decode($results);

//print_r($results);

?>
