JSON to PHP Array error - php

Question

i am having trouble getting a JSON file to a php-array.
i got a json-file as response from an api (request done with curl)
and want to make an array out of it but it won't work.
Here is my code:
<?php
class modExpose{
public static function getFunction($id){
//In my code i am "preparing" the request here
// *********** cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url.$qry_str);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
}
$id = $_GET['id'];
$data = modExpose::getFunction($id);
$array = json_decode($data,true);
print_r($array);
?>
the print_r function only delivers: 1. (same does the var_dump() function).
I also tried adding html_entity_decode() but the problem still remains.
Thank's for helping!

Answer 1

That is probably because the return value of your curl_exec() call is true on success and that is all you are returning from your method.
If you want to get the data that was returned by the curl call, you need to set the CURLOPT_RETURNTRANSFER option:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url.$qry_str);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
// Return the result on success
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
// Now response will contain the results of your curl call
$response = curl_exec($ch);
Apart from that I assume you have checked the variables that seem to be undefined in your example code.
