Detailed explanation of several implementation methods of PHP jump page_PHP tutorial

•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:
void header (string string [,bool replace [,int http_response_code]])
The optional parameter replace indicates Whether to replace the previous similar header or add a header of the same type. The default is to replace.
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 the official forum of Lamp Brothers

Copy the code The code is as follows:

< ?php
>//Redirect the browser
header("Location: http://bbs. lampbrother.net");
//Ensure that subsequent code will not be executed after redirection
exit;
?>

• PHP page jump 2. Meta tag
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, the meta tag is used to automatically jump to the LAMP Brothers Band official forum after the vaccine is released.

Copy code The code is as follows:

< meta http-equiv = "refresh"
content = "1; url=http://bbs.lampbrother.net" >

For example, the following program meta.php implements the page to automatically jump to bbs.lampbrother.net after staying on the page for one second.

Copy code The code is as follows:

< ?php
$ url = "http://bbs.lampbrother .net" ; ?>
< html >
< head >
< meta http-equiv = "refresh" content ="1;
url = < ?php echo $url; ?> " >
< /head >
< body >
The page only stays for one second...
< /body >
< ; /html >

PHP page jump 3. JavaScript
For example, this code can be placed in any legal position in the program.

Copy code The code is as follows:

< ?php
$ url = "http://bbs.lampbrother .net" ;
echo " < script language = 'javascript'
type = 'text/javascript' > ";
echo " window.location.href = '$url' ";
echo " < /script > ";
?>

The above are the three PHP page jump implementation methods we introduced to you.
