PHP: The following code can block PHP attention level error, that is, throw any non-attention errors

[PHP] Error_reporting (e_all&~e_notice);

Error_reporting (E_all&~e_notice);
Open the session method, you can use $_sesion after opening.

The session is something that is stored on the service side OH. After launch, it will send a session ID to the browser, which is the type of cookies

[PHP] Session_Start ();

Session_Start ();
It doesn't matter if the browser disables cookies, so you can write the session to the URL. Hey.

[PHP] session_name. ' = '. session_id ()

Session_name. ' = '. session_id () Attach the adminaction I wrote, only login function oh
