Put JSON content in a JSON file - php

Question

I'm trying to put a JSON response from an API connection into a JSON file but when I do so I only get the value true in the JSON File.
The API PHP function:
public function Get_Reviews(){
$token = 'CDF494791E05F36531FA0F5F';
$headers[] = 'Authorization: Bearer ' . $token;
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => '[URL]',
CURLOPT_HTTPHEADER => $headers
));
$response = curl_exec($curl);
curl_close($curl);
return json_encode($response);
}
and the code to put the response in a JSON file:
$api = new Reviews();
$reviews = $api->Get_Reviews();
$file = "reviews_created.json";
unlink($file);
$fp = fopen($file, 'w');
fwrite($fp, $reviews);
fclose($fp)
When I var_dump($reviews) I get a clean JSON response and I can copy that manually in a JSON file but I need to make this dynamic.
I hope anyone can help me with this.

Check this sample code. It's working fine in my side.
<?php
// Get cURL resource
$curl = curl_init();
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => "your API end point"
));
// Send the request & save response to $resp
$result = curl_exec($curl);
// Close request to clear up some resources
curl_close($curl);
//header('Content-Type: application/json');
//echo $result;
$file = 'product.json';
// Open the file to get existing content
$current = file_get_contents($file);
// Append a new person to the file
$current .= $result;
// Write the contents back to the file
file_put_contents($file, $current);
Note : Give destination JSON file as write permission.
