Sorry, the script contained an error; try the following:

<?php

$file = 'somefile';
$currentdir = '';
$found = false;
while (true) {
// Check if file exists
if ($found = file_exists($file)) {
break;
}

// Prevent infinite loop
if ($currentdir == realpath(dirname($file))) {
break;
}

// Update path
$currentdir = realpath(dirname($file));
$file = "../$file";
}

// Show result
echo basename($file),
$found ?
" found under: " . realpath(dirname($file)) . "; path: $file" :
" not found";

?>
