What best practices should be followed when moving or renaming temporary files in PHP after an upload?

When moving or renaming temporary files in PHP after an upload, it is important to ensure that the file is properly handled to prevent security vulnerabilities and potential issues with file manipulation. One best practice is to use the move_uploaded_file() function provided by PHP, which moves an uploaded file to a new location. This function also performs security checks to ensure that the file is not being moved to a potentially harmful location.

// Example code snippet for moving and renaming a temporary file after upload
$targetDirectory = "uploads/";
$targetFile = $targetDirectory . basename($_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.";
}
