Normalizes a URI by making it syntactically correct.
A stream is referenced as "scheme://target".
The following actions are taken:
$uri: String reference containing the URI to normalize.
The normalized URI.
function file_stream_wrapper_uri_normalize($uri) {
$scheme = file_uri_scheme($uri);
if ($scheme && file_stream_wrapper_valid_scheme($scheme)) {
$target = file_uri_target($uri);
if ($target !== FALSE) {
$uri = $scheme . '://' . $target;
}
}
else {
// The default scheme is file://
$url = 'file://' . $uri;
}
return $uri;
}
