In PHP, serialization is the process of converting a data structure or object into a string representation that can be stored or transmitted. This allows you to save the state of an object or data structure to a database, cache, or send it over a network connection, and then later recreate the object or data structure from the serialized string.
For example, the serialized string for an integer would be i:123, while the serialized string for a string would be s:5:"Hello".
$serializedData); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); curl_close($ch); // Handle the response from the service echo $response; On the external service, you would then use the unserialize() function to convert the serialized data back into a PHP data structure or object. // Get the serialized data from the HTTP POST request $serializedData = $_POST['data']; // Unserialize the data $data = unserialize($serializedData); // Use the data echo "Name: ".
