PHP page jump - common method, php page jump

PHP page jump 1. header() function

The header() function is a very simple method for page jump 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:

<p>void header (string string [,bool replace [,int http_response_code]])</p>

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

The second optional parameter http_response_code forces the HTTP response 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.

2. There cannot be any output before using the header.

3. The PHP code after the header will also be executed. For example, redirect the browser to Guanwei Blog

<p>< ?php<br />//重定向浏览器<br />header("Location: http://www.guanwei.org");<br />//确保重定向后，后续代码不会被执行<br />exit;<br />?></p>

PHP page jump 2, Meta tag

The

Meta tag is a tag in HTML that is 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.

If content="seconds;url=website" is set, it defines how long it takes for the page to jump to the specified URL. For example, use the meta tag to automatically jump to the Guanwei blog after the vaccine.

<p>< meta http-equiv="refresh" content="1;url=http://www.guanwei.org"></p>

For example, the following program meta.php implements the page to automatically jump to www.guanwei.org after staying on the page for one second.

<p>< ?php<br />$url = "http://www.guanwei.org"; ?><br />< html><br />< head><br />< meta http-equiv="refresh" content="1; url=< ?php echo $url; ?>"><br />< /head><br />< body><br />页面只停留一秒&hellip;&hellip;<br />< /body><br />< /html></p>

PHP page jump 3, JavaScript (commonly used, recommended)

For example, this code can be placed anywhere in the program that is legal.

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