PHP包括不工作？ 我正在使用文件路径在chrome上打开

Question

I want to add a nav bar using php include, but I have it in a loop in the navBar.php file:

<?php
$Links = array("index.php", "page1.php", "page2.php");
$Text = array("Home", "page1", "page2");
$ReqPage = (explode('/', $_SERVER['SCRIPT_NAME']));
echo $ReqPage[2];
$Nav="
<div id=\"navwrapper\">

          <div id=\"nav\">

          <ul id=\"navstuff\">
";
$j = 0;
foreach($Links as $ALink){
    if ($ALink == $ReqPage){
        $Nav .= "<li class=\"selected\"><a href=\"#\">";
    } else{
        $Nav .= "<li><a href=\"$ALink\">";
    }
    $Nav .= "$Text[$j]</a></li>
";
    $j++;
}
$Nav .= "</ul>

        </div>

        </div>
";
echo $Nav;
?>

I have it in my index.php file as <?php include("navBar.php"); ?>. It is not showing anything. Is it because I am not running off of a server? Currently I am opening the file by just typing in the file path into Chrome. Do I have to use a server for this? Also, If I have to use a server, what are some good ones for my computer (I don't want to pay money for large external servers)?

Answer 1

Yes you need to run server software that has php functionality installed.

I would recommend Apache+PHP which will run on your local machine and won't cost you anything.

Search for an installation guide for beginners.

EDIT:

Actually all you need is PHP. It has an inbuilt web server which would be perfect for testing on a local machine.
