How can absolute file paths be used instead of relative paths in PHP file uploads?

When uploading files in PHP, using absolute file paths instead of relative paths can provide more control and accuracy in specifying the exact location of where the file should be saved. To use absolute file paths, you need to determine the full path of the directory where you want to save the uploaded files on the server. This can be achieved by using the `__DIR__` magic constant to get the current directory path and then appending the desired folder name to it. 

$uploadDir = __DIR__ . '/uploads/';
$uploadedFile = $uploadDir . basename($_FILES['file']['name']);

if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadedFile)) {
    echo "File uploaded successfully!";
} else {
    echo "Error uploading file.";
}
