PHP - get json data from url - php

Question

I'm trying to load json data from this url =
http://api.opencagedata.com/geocode/v1/json?query=48.84737%2C2.28605&pretty=1&no_annotations=1&no_dedupe=1&key=b61388b5a248b7cfcaa9579ed290485b
Using file_get_contents works with other json urls but this one is strange. It returns only "{" the first line. Strlen gives 1480 which is right.Substr(2,18) gives "documentation" which is right too. But still i can't echo the entire text. Maybe there's some way to read the text line by line and save it in another string ? The entire text is still fully loaded in the textfile
Here's the php code i tried
<?php
$url = file_get_contents("http://api.opencagedata.com/geocode/v1/json?query=48.84737%2C2.28605&pretty=1&no_annotations=1&no_dedupe=1&key=b61388b5a248b7cfcaa9579ed290485b");
$save = file_put_contents("filename.txt", $url);
echo $url;
?>
Also tried this function but still same.
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}

You can get return value with json_decode.
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return json_decode($data,true);
}
