Three types of PHP jump page

PHP three ways to jump 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 code

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.

2. $url ?=? "Http://blog.csdn.net/abandonship" ;? ??
