How can the issue of the photo not being uploaded be resolved in the PHP script?

The issue of the photo not being uploaded in the PHP script can be resolved by checking for any errors during the file upload process. This can be done by checking the `$_FILES['file']['error']` variable and handling any potential errors accordingly. Additionally, make sure that the file upload form has the correct `enctype="multipart/form-data"` attribute. 

if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $uploadDir = 'uploads/';
    $uploadFile = $uploadDir . basename($_FILES['file']['name']);

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