How can the move_uploaded_file function be used effectively to securely move files to a different location in PHP?

When using the move_uploaded_file function in PHP to move files to a different location, it is important to ensure that the destination directory is secure and that proper validation is done on the uploaded file. This helps prevent unauthorized access and potential security vulnerabilities. One way to securely move files is to check the file type, size, and ensure that the destination directory has the correct permissions set.

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

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