error using include_once with a php variable

My code is like this:

<?php   // file location: include/config.php
    $CONFIG["DIRECTORY"]["HTMLINC"] = "http://127.0.0.1/mysite/html_include";
?>

,

<?php   // file location: ./template.php
    require_once("include/config.php");
    // ...
    require($CONFIG["DIRECTORY"]["HTMLINC"] . "/anotherpage.php"); // Doesn't work
?>

It gives the following warning message:

Warning: require(): http:// wrapper is disabled in the server configuration by allow_url_include=0 in…

I’m currently testing the code in my local server, so I can easily change the value of allow_url_include. But I will eventually upload this code to a remote server. I cannot guaranty that allow_url_include will always be set to 1.

How do I prevent this warning message and make this code work?

Answer 1

that isn’t an absolute path. that is a URL. the absolute path would be the path to the file on disk. If you go to /var/www/mysite/html_include to access the file to edit it, that is the absolute path. You would want to set $CONFIG["DIRECTORY"]["HTMLINC"] to that absolute path. You can use $_SERVER['DOCUMENT_ROOT'] to get the web root supplied by apache and append the /mysite/html_include to generate the right path. ideally you would probably have a separate config variable called something like APP_ROOT that is the document root + /mysite (the absolute path to your application). something like:

<?php
$CONFIG["DIRECTORY"]["APP_ROOT"] = $_SERVER['DOCUMENT_ROOT'].'/mysite';
$CONFIG["DIRECTORY"]["HTMLINC"] = $CONFIG["DIRECTORY"]["APP_ROOT"].'/html_include';

This would allow you to use APP_ROOT for other variables too:

$CONFIG["DIRECTORY"]["UPLOADS"] = $CONFIG["DIRECTORY"]["APP_ROOT"].'/uploads';
$CONFIG["DIRECTORY"]["IMAGES"] = $CONFIG["DIRECTORY"]["APP_ROOT"].'/images';
$CONFIG["DIRECTORY"]["THUMBNAILS"] = $CONFIG["DIRECTORY"]["APP_ROOT"].'/thumbs';

etc.
