I spent the last two hours wondering what was wrong with my if statement: file_exists($file) was returning false, however I could call include($file) with no problem.

It turns out that I didn't realize that the php include_path value I had set in the .htaccess file didn't carry over to file_exists, is_file, etc.

Thus:

<?PHP
// .htaccess php_value include_path '/home/user/public_html/';

// includes lies in /home/user/public_html/includes/

//doesn't work, file_exists returns false
if ( file_exists('includes/config.php') )
{
     include('includes/config.php');
}

//does work, file_exists returns true
if ( file_exists('/home/user/public_html/includes/config.php') )
{
    include('includes/config.php');
}
?>

Just goes to show that "shortcuts for simplicity" like setting the include_path in .htaccess can just cause more grief in the long run.
