function StreamWrapperManagerInterface::isValidScheme

Checks that the scheme of a stream URI is valid.

Confirms that there is a registered stream handler for the provided scheme and that it is callable. This is useful if you want to confirm a valid scheme without creating a new instance of the registered handler.

Parameters

string $scheme: A URI scheme, a stream is referenced as "scheme://target".

Return value

bool Returns TRUE if the string is the name of a validated stream, or FALSE if the scheme does not have a registered handler.
