PHP Coding Tricks: The Use of Root Path and Require_once

Avoid Using Relative Paths
In PHP coding practices, using relative paths should be avoided as they can cause uncertainty in file inclusion, especially when the folder structure becomes more complex. A relative path depends on the location of the calling file rather than the file being called. This can potentially lead to errors when the application is executed from different directories. Instead, it is recommended to use absolute paths with the help of constants or manually define the root path to ensure files are always included from a consistent location, improving code readability and maintainability.

Avoid Using require, include, require_once, or include_once
In PHP development, using require, include, require_once, or include_once often leads to issues in dependency management and code structure. While these functions are used to include external files, they can cause duplicate calls, errors if the file is missing, and complicate debugging in large projects. As a safer and more modern alternative, it is recommended to use autoloading, such as the Composer Autoload feature or the spl_autoload_register() function. With this approach, dependencies are managed automatically, improving code efficiency and ensuring that the required files are always available without manually including each one.
