How can serialization and rawurlencode be used to pass arrays in PHP?

To pass arrays in PHP, serialization can be used to convert the array into a string that can be easily passed as a parameter in a URL. Additionally, using rawurlencode ensures that the serialized array is properly encoded for transmission. Upon receiving the serialized and encoded array, it can be deserialized and processed back into an array within the PHP script. 

// Serialize the array
$array = [1, 2, 3];
$serializedArray = serialize($array);

// Encode the serialized array for URL transmission
$encodedArray = rawurlencode($serializedArray);

// Pass the encoded array as a parameter in a URL
$url = "example.com/script.php?data=$encodedArray";

// Retrieve the encoded array from the URL parameter
$receivedEncodedArray = $_GET['data'];

// Decode the received encoded array
$decodedArray = rawurldecode($receivedEncodedArray);

// Deserialize the decoded array back into an array
$receivedArray = unserialize($decodedArray);

// Process the received array
print_r($receivedArray);
