PHP Fatal Error: Double Class Declarations

If you encounter the "PHP Fatal error: Cannot redeclare class" message, it indicates that you have multiple declarations of a class with the same name. This typically occurs due to multiple file inclusions.

To resolve this issue, utilize the include_once function when including external PHP files. This ensures that a particular file is included only once, preventing duplicate class declarations.

include_once "something.php";

It's crucial to be mindful of potential dependency chains in your code. Sometimes, multiple files can be included within each other, leading to unintentional class redeclaration. Carefully consider the include dependencies to avoid this error.
