PHP is writing this error in the logs Notice Use of undefined constant

The error message "Notice: Use of undefined constant" in PHP typically occurs when you reference a constant that has not been defined or is not in scope.

To resolve this error, you can follow these steps:

1. Ensure that you are using the correct constant name: Make sure that the constant name you are using is spelled correctly and matches the one defined elsewhere in your code.

2. Define the constant: If you haven't defined the constant yet, use the define() function to define it before using it. For example: define('CONSTANT_NAME', 'constant_value');

3. Check the scope: Make sure the constant is defined within the appropriate scope. If the constant is defined within a function or class, ensure that you are referencing it within the same scope.

4. Use constant with proper syntax: When using a constant, make sure to prefix it with the constant name followed by the scope resolution operator :: if it's a class constant or use the constant name directly if it's a global constant.

By following these steps, you should be able to resolve the "Notice: Use of undefined constant" error in your PHP code
