How to Retrieve JSON Objects and Extract Data from URLs Using PHP?

Retrieve JSON Objects and Extract Data from URLs Using PHP

In this discussion, we tackle a prevalent programming challenge: extracting specific data from a JSON object retrieved from a given URL. To accomplish this succinctly, PHP offers several approaches.

Using file_get_contents

This method is straightforward and utilizes the file_get_contents function. However, it necessitates enabling the allow_url_fopen setting:

ini_set("allow_url_fopen", 1);
$json = file_get_contents('url_here');
$obj = json_decode($json);
echo $obj->access_token;

Leveraging cURL

Alternatively, you can leverage cURL for enhanced security and compatibility:

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'url_here');
$result = curl_exec($ch);
curl_close($ch);

$obj = json_decode($result);
echo $obj->access_token;

By adopting either of these approaches, you can efficiently retrieve the desired JSON object and extract the necessary data.
