Is urlencode() a recommended method for passing complex variables in PHP?

When passing complex variables in PHP, urlencode() is not the recommended method as it may not handle all types of data properly. Instead, it is better to use serialize() or json_encode() to encode complex variables before passing them and then decode them using unserialize() or json_decode() on the receiving end. 

// Encoding complex variable using json_encode()
$complexVariable = ['key1' => 'value1', 'key2' => ['nestedKey1' => 'nestedValue1']];
$encodedComplexVariable = json_encode($complexVariable);

// Decoding complex variable using json_decode()
$decodedComplexVariable = json_decode($encodedComplexVariable, true);
