What is the best practice for passing an array value through a POST request in PHP?

When passing an array value through a POST request in PHP, the best practice is to serialize the array before sending it and then unserialize it on the receiving end. This ensures that the array data is preserved and can be easily manipulated. 

// Serialize the array before sending it through a POST request
$array = [1, 2, 3];
$postData = http_build_query(['array' => serialize($array)]);

// Send the POST request
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// Unserialize the array on the receiving end
$data = unserialize($_POST['array']);
