What are you asking?
Relative paths??

NogDog

Hard to say without more specifics on what you are really looking for.

Possibly what you're interested in is the super-global variable $_SERVER['DOCUMENT_ROOT']?

that link dsnt work.

<?php

$dr = $_SERVER["DOCUMENT_ROOT"].'/index.php';

echo <<<html
<a href="$dr">home</a>
html;

RayPooley

nb6 This ..

    <?php
$dr = $_SERVER["DOCUMENT_ROOT"].'/index.php';
echo "<a href=\"<?=$dr ?>\">home</a>";
?>

This .......

   $dr = $_SERVER["DOCUMENT_ROOT"].'/index.php';
   echo "<a href=\"".$dr."\">home</a>";

Oh, so it's nothing to do with folders. It's about URLs.

echo "<a href='/index.php'>home</a>";

NogDog

Of course, the web server (e.g. Apache or other options) has to be configured to know where the home directory is on the server's file system, but that's separate from PHP.

NogDog

RayPooley That would end up with a URL something like...

"https://var/www/html/my_project/index.php"

...which ~99.999% of the time will not be what you want.

Yes. Should be ....

   $dr = $_SERVER["DOCUMENT_ROOT"].'/index.php';
   echo "<a href=\"".$dr."\">home</a>";

which renders as a link "home" that links to the absolute path

<a href="C:\inetpub\wwwroot/index.php">home</a>

in my case.

Should have tested it.
