Summary of definitions of common PHP header and phpheader header _ PHP Tutorial

A summary of common PHP header definitions and a summary of phpheader headers. The PHP header definition is summarized, and the phpheader header summary header () function sends the original HTTP header to the client. It is important to realize that the actual output must be summarized by the header definitions commonly used by PHP, and the phpheader header must be summarized.

The header () function sends the original HTTP header to the client.

It is important to realize that the header () function must be called before any actual output is sent (in PHP 4 and later versions, you can use the output cache to solve this problem):

Phpheader ('http/1.1 200 OK '); // OK normal access header ('http/1.1 404 Not Found '); // notify the browser that the page does not contain the header ('http/1.1 301 Moved Permanently '); // Set the address to be Permanently redirected to the 301 header ('Location: http://www.ithhc.cn/ '); // Jump to a new address header ('refresh: 10; url = http://www.ithhc.cn/ '); // The delayed redirection header ('x-Powered-By: PHP/6.0.0 '); // modify the X-Powered-By header ('content-language: en'); // The header of the document language ('content-Length: 6666 '); // set the content length header ('last-Modified :'. gmdate ('d, d m y h: I: S', $ time ).
