note 114042 modified in function.spl-autoload-register by tularis

if you have a dir-structure like "/abc/def/ghi", your index.php lies in the top directory, but you want to use namespaces starting with "def" or "ghi": you can switch the namespace root directory of php with e.g. set_include_path(__DIR__ . '/abc') and afterwards define + use your namespaces with the simple spl_autoload_register() function without any arguments supplied. remember that php handlers "cli" and "cli-server" are special cases. --was-- sorry my last comment contained an error and might be deleted. this is the corrected version: if you have a dir-structure like "/abc/def/ghi", your index.php lies in the top directory, but you want to use namespaces starting with "def" or "ghi": you can switch the namespace root directory of php with e.g. set_include_path(__DIR__ .
