You're using the wrong function to check if the file exists and you are not
preventing an infinite loop. Try running the following code:
<?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 paths
$file = "../$file";
$currentdir = realpath(dirname($file));
}
// Show result
echo basename($file),
$found ?
" found under: " . realpath(dirname($file)) :
" not found";
?>
