The first way: header()

The main function of the header() function is to output the HTTP protocol header (header) to the browser.

Syntax:

void header ( string $string [, bool $replace = true [, int $http_response_code ]] )

The optional parameter replace specifies whether to replace the previous similar header or add a header of the same type. The default is to replace.

The second optional parameterhttp_response_codeForce the HTTP corresponding code to the specified value. The Location type header in the header function is a special header call, often used to implement page jumps. Note: 1. There cannot be a space between location and ":", otherwise it will not jump.

Example:

Note:

• There cannot be any output before the header is executed

• ##location and : There can be no spaces between

• The php code after the header will still be executed, so you need to pay attention to using exit;

Second One way: meta tag

< meta http-equiv="refresh" content="1;url=http:// www.baidu.com">

The third way: javascript

< ?php $url = "http://www.baidu.com"; echo "< script language='javascript' type='text/javascript'>"; echo "window.location.href='$url'"; echo "< /script>"; ?>
