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]View Plaincopyprint?
    1. < PHP
    2. redirect Browser
    3. Header ("location:http://blog.csdn.net/abandonship");
    4. Ensure that subsequent code is not executed after redirection
    5. Exit
    6. ?>

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]View Plaincopyprint?
    1. <?php
    2. $url = "Http://blog.csdn.net/abandonship";
    3. ?>
    6. <meta http-equiv="Refresh" content="1;url=<?php echo $url;?>" >
    8. <body>
    9. It ' s transit station.
    10. </body>

PHP page Jump Third, JavaScript

[PHP] view plaincopyprint?
    1. <?php
    2. $url = "Http://blog.csdn.net/abandonship";
    3. echo "<script type= ' text/javascript ' >";
    4. echo "window.location.href= ' $url '";
    5. echo "</script>";
    6. ?>
