What are the limitations of passing arrays through GET requests in PHP?

When passing arrays through GET requests in PHP, the values are converted to strings and the array structure is lost. To solve this issue, you can serialize the array before passing it in the URL and then unserialize it on the receiving end to restore the array structure. 

// Serialize the array before passing it in the URL
$array = array('value1', 'value2', 'value3');
$serialized_array = serialize($array);

// Pass the serialized array in the URL
$url = 'http://example.com/script.php?data=' . urlencode($serialized_array);

// On the receiving end, unserialize the array
$received_array = unserialize($_GET['data']);
print_r($received_array);
