Description

spl_autoload(string $class, ?string $file_extensions = null): void

file_extensions: By default it checks all include_paths to contain filenames built up by the lowercase class name appended by the filename extensions .inc and .php.

Return Values

Errors/Exceptions

Throws LogicException when the class is not found and there are no other autoloaders registered.
