Are there any specific PHP functions or libraries that can simplify the file upload and renaming process?

When uploading files in PHP, it's common to want to rename the file to avoid conflicts or improve organization. One way to simplify this process is by using the `move_uploaded_file()` function along with generating a unique filename using `uniqid()` or `md5()`. 

// Example code to handle file upload and renaming
$targetDirectory = "uploads/";
$targetFile = $targetDirectory . uniqid() . '_' . basename($_FILES["fileToUpload"]["name"]);

if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $targetFile)) {
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
    echo "Sorry, there was an error uploading your file.";
}
