How can performance optimization techniques, such as profiling and function abstraction, be applied to improve the efficiency of handling default values in PHP scripts?

Handling default values in PHP scripts can sometimes lead to inefficiencies, especially when dealing with multiple conditional checks. To improve efficiency, one can use performance optimization techniques such as profiling to identify bottlenecks and function abstraction to streamline the handling of default values. 

<?php

// Profiling to identify bottlenecks
// Example: use Xdebug or Blackfire.io to analyze the performance of the script

// Function abstraction to streamline handling of default values
function getValueOrDefault($value, $default) {
    return isset($value) ? $value : $default;
}

// Usage of the function
$name = getValueOrDefault($_POST['name'], 'Guest');

echo "Hello, $name!";

?>
