stream_register_wrapper
This seems to be a great alternative to file_exists.
if( file_exists(__DIR__.'/som-file.php') )
Goes way slower than:
if( stream_resolve_inlcude_path(__DIR__.'/som-file.php') !== false)

stream_resolve_include_path() seems to cache it's output. After I renamed a file, I had to restart Apache for stream_resolve_include_path() to not return non-existing file name. This was on Windows.

It really behaves like `include` and will only resolve the filename against the include-path, if the path is relative. It makes not much sense to resolve already absolute pathnames anyway.
