How does PHP handle memory allocation and deallocation when a script is reloaded after submitting a form, and what happens to objects and variables in this scenario?

When a PHP script is reloaded after submitting a form, the memory allocated for variables and objects is automatically released by the PHP garbage collector. This ensures that resources are properly managed and memory is not wasted. It is important to properly unset variables and objects that are no longer needed to free up memory. 

// Example of unsetting variables and objects after form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    
    // Unset variables and objects that are no longer needed
    unset($variable1, $variable2, $object1);
}
