You are writing a PHP script and you need to set a value that should not change throughout the execution of the script. How would you do this?

To set a value that should not change throughout the execution of a PHP script, you would define a constant using the define() function. Constants are values that remain fixed and cannot be changed once defined. They provide a way to store fixed values that are accessible throughout the script. By using define(), you can create a constant with a specific name and value that remains constant throughout the script's execution. Learn more: https://www.php.net/manual/en/function.define.php
