Using __autoload() is deprecated
Defining the __autoload() function used to be the way to create a autoloading mechanism for classes, traits, interfaces and enumerations. This was later replaced by the spl_autoload_register() function, which allows adding and removing autoloading functions. Ever since, creating the __autoload() function is reported as deprecated, and the function is not used since PHP 8.0.
PHP code

function __autoload() {}
