API has redirecting page - PHP - php

Question

I need to send data to an API using PHP. The API has a redirect page before showing the final result. The following code shows the content of the redirecting page rather than the final result. How can I wait until the final result?
$url = 'https://example.com/api';
$data = array('text' => "try");
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'GET',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }
echo $result;
P.S. I got this code from one of stackoverflow's questions.

You could use cURL to get the final response, using CURLOPT_FOLLOWLOCATION:
From documentation :
CURLOPT_FOLLOWLOCATION: TRUE to follow any "Location: " header that the server sends as part of the HTTP header (note this is recursive, PHP will follow as many "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is set).
$url = 'https://example.com/api';
$data = array('text' => "try");
$full_url = $url . (strpos($url, '?') === FALSE ? '?' : '')
. http_build_query($data) ;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $full_url) ;
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Content-type: application/x-www-form-urlencoded',
]);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close ($ch);
var_dump($response) ;
