How can variables be utilized effectively to handle changing file paths in PHP file upload scripts?

When dealing with changing file paths in PHP file upload scripts, using variables can provide a flexible solution. By assigning the base file path to a variable, you can easily update it in one place if the file structure changes. This allows for easier maintenance and scalability of the script. 

// Define base file path
$uploadPath = "/var/www/uploads/";

// Concatenate base path with uploaded file name
$targetFile = $uploadPath . basename($_FILES["fileToUpload"]["name"]);

// Move uploaded file to the specified path
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $targetFile)) {
    echo "File uploaded successfully.";
} else {
    echo "Error uploading file.";
}
