What is the significance of using constant values as default parameters in PHP functions?

Using constant values as default parameters in PHP functions can help improve code readability and maintainability. By defining constants for default parameter values, it becomes easier to understand the purpose of the parameter and its expected value. Additionally, if the default value needs to be changed in the future, it can be done in one central location by updating the constant value, rather than searching and updating all function calls. 

<?php

define('DEFAULT_LIMIT', 10);

function fetchData($limit = DEFAULT_LIMIT) {
    // Function implementation
}

// Call the function with default parameter
fetchData();

?>
