Is it advisable to pass serialized arrays via HTTP in PHP applications due to security concerns?

Passing serialized arrays via HTTP in PHP applications can pose security risks as it can be vulnerable to attacks like SQL injection or code injection. It is advisable to avoid passing serialized arrays directly and instead use JSON encoding for data transfer, as it is more secure and easier to validate on the receiving end.

// Serialize the array
$data = serialize($array);

// Encode the serialized data to JSON
$jsonData = json_encode($data);

// Send the JSON data via HTTP
// Example: 
// $url = 'http://example.com/api';
// $ch = curl_init($url);
// curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
// curl_exec($ch);
