Question

Here is my code – not sure why it isn’t working:

<?php
$urlroot      = $_SERVER['HTTP_HOST'];
$urllink      = "http://" . $urlroot;
$DirPath      = getcwd() . "\n";
$InnermostDir = basename(rtrim($DirPath, '/'));
if ($InnermostDir == $urlroot) {
    $InnermostDir = 'home';
    echo $InnermostDir;
};
?>

If I do an echo on $InnermostDir and $urlroot, they both show the domain example.com. So not sure why this won’t return true?

Answer 1

$DirPath contains a \n at the end, which is not removed, therefore the strings won’t be equal.

rtrim($DirPath, '/') will only remove / characters from the end, not the \n. If you want it to remove the \n as well, you need to use rtrim($DirPath, "/\n"), or simply don’t add that \n when setting $DirPath.
