What could be the potential reasons for a file not being found in a subdirectory, even though it exists?

The potential reasons for a file not being found in a subdirectory, even though it exists, could include incorrect file path, file permissions, or the file being hidden. To solve this issue, you should double-check the file path, ensure that the file has the correct permissions set, and check if the file is not hidden or restricted in any way. 

$file_path = 'subdirectory/file.txt';

if (file_exists($file_path)) {
    // File exists, do something with it
    echo "File found!";
} else {
    echo "File not found!";
}
