如何使用 PHP 仅注入 PHP 页面的某些部分 [英] How to I inject only certain parts of PHP page using PHP

问题描述

I know I can include other files using PHP

<?php include("file.php"); ?>

Now my question is how do I inject only certain parts of "file.php"?

Lets say I have some header code and some footer code within file.php. How do I organize file.php with the correct separated section, and how do only include certain sections of the file.php (file.php?footer or something like that?)

解决方案

The easiest (and usual) way is to simply make separate header.php and footer.php files, and access them where you need them. There's no direct support for only loading parts of a file.

Edit (to respond to your comment on the other answer about using separate functions): Let's say your file.php looks like this:

<?php

function header() { ?>
   header content goes here
<?php }

function footer() { ?>
    footer content goes here
<?php }

?>

Then in the page you're calling it into, you can use <?php header() ?> and <?php footer() ?> to produce the content where you want it.
