What's the problem?

What's the problem? session_start (); & nbsp; $ _ SESSION [& quot; login & quot;] = & quot; YES & quot; & nbsp; $ _ SESSION [& quot; name & quot;] = $ name; how can I obtain S on other pages?
Session_start ();
$ _ SESSION ["login"] = "YES ";
$ _ SESSION ["name"] = $ name;
How can I get the name value of the SESSION on another page? I use $ reader =$ _ SESSION ["name"] on another page. no value can be obtained.

------ Solution --------------------
Do other pages have session_start?
------ Solution --------------------
Session_start (); the first row must be added. There must be no leading space.

When I was in Baidu, I saw some people say no.
It's a cool child.
