Php 包括“file.php + 链接”

Question

Is it possible to use "php include" that calls the first link existing in another.php file.

Here below how my files are structured. What I trying to do is to click PROJECT which will open the file project-one.html

I guess:first-child does not work in the HTML file...

in the HTML file I have:

<ul>
<li><?php include 'menu.php:first-child';?>PROJECT</li>
</ul>

in the PHP file I have:

<ul>
<li><a href="project-one.html">P1</a></li>
<li><a href="project-two.html">P2</a></li>
</ul>

If you want to have a file that centralises the link creation, you could do like so:

index.php <- you need this file to be PHP (regular HTML files won't run include and php functions and code)

<?php
include 'linkgenerator.php';
?>

<ul>
<li><?php renderlink(1); ?></li>
</ul>

linkgenerator.php

<?php
function renderlink($linknumber) {
    if ($linknumber == 1) {
        echo "<a href="project-one.html">P1</a>";
    } else if ($linknumber == 2) {
        echo "<a href="project-two.html">P2</a>";
    } 
}

A proper implementation would involve more advanced concepts, but if you are learning this is a good starting point to understand the principles.
