如何使用PHP来调用信息并发布到另一个网页

I am making a website and have a pretty strong template that I have made. Of course, I need to make changes to it once and a while and would like to figure out a way to make changes to only one .php file rather than having to change 10+ different files. There has to be a way to do this in php, I just do not know where to look.

The easiest way to do this is to create a separate file which you can use as an include file in your scripts.

for instance, here a header script:

<?php

   $title = 'this is the title';

?>

and name it something like header.php

Then all you need to do is to put something like this in each page that has the updates:

include_once('header.php');

you can do it by using htaccess, make rewrite rule like this

make index.php with your template and blank file demo.php

RewriteRule ^home$ index.php RewriteRule ^Demo$ index.php?page=demo.php

and put this code in your body part of index.php file

$page = isset ( $_REQUEST [ 'page' ] ) ? $_REQUEST [ 'page' ] : 'home' ;
if ( $page !== 'home' && strlen ( $page ) > 0 ) {
     $file = sprintf ( '%s' , $page ) ;
     if ( file_exists ( $file ) ) {
            require_once $file ;
     };
} else require_once 'default page you wanna show' ;

and brows to www.yoursite/Demo

you will redirect to demo.php with your theme
