How can PHP beginners avoid sending corrupted attachments in email forms?

To avoid sending corrupted attachments in email forms, PHP beginners can use the PHP `move_uploaded_file()` function to move the uploaded file from the temporary directory to a specified location. This ensures that the file is properly handled and attached to the email without being corrupted. 

// Check if file was uploaded successfully
if ($_FILES['attachment']['error'] === UPLOAD_ERR_OK) {
    $tempFile = $_FILES['attachment']['tmp_name'];
    $destination = 'uploads/' . $_FILES['attachment']['name'];

    // Move uploaded file to specified location
    if (move_uploaded_file($tempFile, $destination)) {
        // Attach the file to the email
        $mail->addAttachment($destination);
    } else {
        echo 'Failed to move uploaded file.';
    }
} else {
    echo 'Error uploading file.';
}
