It appears to return incorrectly for 'file://' wrapper which I would consider to be local.



CODE:

$file1 = '/somefile.jpg';

$file2 = 'file://shouldbelocal.jpg';

$file3 = 'http://someotherfile.jpg';



$local = stream_is_local($file1);

$shouldbelocal = stream_is_local($file2);

$remote = stream_is_local($file3);

var_dump($local, $shouldbelocal, $remote);



RESULT:

bool(true)

bool(false)

bool(false)

this is not a bug

mounting a remote filesystem locally "imports" it so it is available to userland programs like a local directory.

The function stream_is_local() does not work with remote mounts points, like sshfs mount points (it will return true as if it was local).
