PHP-based protocols and encapsulation protocols supported by PHP include many built-in URL-style encapsulation protocols, which can be used for encapsulation such as fopen (), copy (), file_exists (), and filesize () file system functions. In addition to these encapsulation protocols, you can also use stream_wrapper_register () to register custom encapsulation protocols.
Note: The URL syntax used to describe an Encapsulation Protocol only supports the syntax of scheme. Scheme:/And scheme: the syntax is not supported.
