How to jump to a new window in php: 1. Use the [header()] function to output the HTTP protocol header to the browser; 2. Use the meta tag to provide document meta information tags, which can realize page jumps. ;3. Use javascript to automatically jump to the new address.
php method to jump to a new window:
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:
<html> <?php /* This will give an error. Note the output * above, which is before the header() call */ header('Location: http://www.example.com/'); exit; ?>
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 tag is a tag in HTML responsible for providing document meta-information. Using this tag in a PHP program can also achieve page jumps. If http-equiv is defined as refresh, when the page is opened, it will jump to the corresponding page within a certain period of time based on the value specified by content.< meta http-equiv="refresh" content="1;url=http:// www.baidu.com">
The third way: javascript
By using windows.location.href='url'; the page automatically jumps to the new address< ?php $url = "http://www.baidu.com"; echo "< script language='javascript' type='text/javascript'>"; echo "window.location.href='$url'"; echo "< /script>"; ?>
