Three ways to redirect PHP pages

PHP page Jump One, header () function

The header () function is a very simple way to jump a page in PHP. The main function of the header () function is to output the HTTP protocol header (header) to the browser.

The header () function is defined as follows:

void header (String string [, bool replace [, int http_response_code]])

The optional parameter, replace, indicates whether to replace the previous similar header or to add a header of the same type, which is replaced by default.

The Second optional parameter, Http_response_code, forces the HTTP corresponding code to be set to the specified value. The header of the location type in the header function is a special header call that is commonly used to implement page jumps. Note: There can be no spaces between 1.location and ":", otherwise it will not jump.

2. There can be no output before using the header.

PHP code after 3.header will also be executed. For example

< PHP   //Redirect Browser   header ("location:http://www.php.cn");   Ensure that subsequent code is not executed after redirection   ;  >

PHP page jump two, meta tags

The META tag is the tag in HTML that is responsible for providing the meta-information of the document, which can be used in a PHP program or a page jump. If you define HTTP-EQUIV as refresh, the page will be opened to the appropriate page for a certain amount of time based on the values specified in the content. If you set content= "seconds; url= url", you define how long it takes for the page to jump to the specified URL.

< meta http-equiv= "refresh" content= "1;url=http://blog.csdn.net/abandonship" >

example, the following program meta.php implementation of the page after a second to stop the page automatically jump.

<?php     $url = "http://blog.csdn.net/abandonship";   ? >   
PHP page Jump Third, JavaScript

<?php    $url = "Http://blog.csdn.net/abandonship";  echo "<script type= ' text/javascript ' >";  echo "window.location.href= ' $url '";  echo "</script>";   ? >
