If there should be an exit after the header function in PHP

Source: Internet
Author: User

There are usually three kinds:

The code is as follows Copy Code

Location:xxxx:yyyy/zzzz

Content-type:xxxx/yyyy

status:nnn xxxxxx

Common examples

1. Implement Redirection (Status code 302)

The code is as follows Copy Code

<?php
Header ("Location:http://www.111cn.net");
Exit
?>

Example

The code is as follows Copy Code
<?php
Header ("location:http://www.111cn.net/");
Exit ();
File_put_contents ($_server[' document_root '). Directory_separator. " N.txt ", ' PHP Programmer tutorial Network ', LOCK_EX);

If the PHP file runs through a header ("Location: a page URL"), the statement jumps directly to another page, but the jump here does not affect the continuation of the current PHP file. That is to say, after the PHP header jump, the current page of the script will continue to execute. If you need to terminate the script, you need to add exit () or Die ().


But there's no need for some usage.

404 Code

tr>
copy code

<?php 
Header ( ' http/1.1 404 Not Found '),  
Header ("status:404 not Found");  
?

301

<?
Header ("http/1.1 301 Moved permanently");
Header ("location: www.111cn.net");
?
