In PHP URL jump regardless of that approach is inseparable from the header function, below I will give you some commonly used URL jump implementation procedures and attention, there is a need for friends to refer to.

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. Attention:

1.location and ":" Can not have spaces between, otherwise will not jump.

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

PHP code after 3.header will also be executed. For example, redirect the browser to linzl.com

< PHP
redirect Browser
Header ("Location:http://www.111cn.net");
Ensure that subsequent code is not executed after redirection
Exit
?>

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.

For example, the following program meta.php the page to automatically jump to www.guanwei.org after a second stay in the page.

<?php$url= "http://www.guanwei.org";?>

<meta;; url=<?php echo $url;?>>

<body> page only for one second </body>

PHP page Jump Three, JavaScript (common, recommended)

For example, this code can be placed in any legitimate location in the program.

<?php

$url = "http://www.guanwei.org";

echo "<script language= ' javascript ' type= ' text/javascript ' >";

echo "window.location.href= ' $url '";

echo "</script>";

?>

In addition to these methods, I believe we also have their own methods, before we introduced a lot of articles about Phpheader, we can pay attention to topic.alibabacloud.com reference.
