Are there any potential security risks or vulnerabilities associated with moving uploaded files to a temporary folder before final storage?

Moving uploaded files to a temporary folder before final storage can introduce security risks if the temporary folder is not properly secured. This can potentially allow unauthorized access to the files during the temporary storage phase. To mitigate this risk, ensure that the temporary folder has restricted access permissions and is not accessible to the public. 

// Specify the temporary folder for uploaded files
$uploadTempDir = 'uploads/temp/';

// Move uploaded file to temporary folder
move_uploaded_file($_FILES['file']['tmp_name'], $uploadTempDir . $_FILES['file']['name']);
