What are the best practices for handling file uploads in PHP to ensure that the files are not lost during redirection?

When handling file uploads in PHP, it is important to use server-side temporary storage to ensure that the files are not lost during redirection. One way to achieve this is by moving the uploaded file to a temporary directory on the server before processing it further. This way, even if the user is redirected to another page or if an error occurs during processing, the file will still be available for retrieval. 

// Handle file upload
if(isset($_FILES['file']) && $_FILES['file']['error'] == UPLOAD_ERR_OK) {
    $tempFilePath = $_FILES['file']['tmp_name'];
    $targetFilePath = 'uploads/' . $_FILES['file']['name'];

    // Move uploaded file to temporary directory
    move_uploaded_file($tempFilePath, $targetFilePath);

    // Process the file further
    // Redirect or display success message
} else {
    // Handle file upload error
    // Redirect or display error message
}
