PHP header 301/404 Jump to note the detailed _php tutorial

If your page appears 301 or 404 for the user experience is a very serious problem, so we do php header301 or 404 must be careful and careful, and I came to see.

301 Jump

The code is as follows	Copy Code
Header (' http/1.1 301 Moved permanently '); Header (' location:http://www.abc.com/aaa/'); Exit ();

Do not miss the header (' http/1.1 301 Moved permanently '); Or you can't return 301.

404 error page

The code is as follows	Copy Code
Header ("http/1.1 404 Not Found");

If the above does not work, you can try the following:

The code is as follows	Copy Code
Header ("status:404 not Found");

So in order to be foolproof, can be written in two sentences:

The code is as follows	Copy Code
Header ("http/1.1 404 Not Found"); Header ("status:404 not Found");

Tips,

If we write the code we have to use webmaster tools to test the return status is not what we want oh.
