In PHP, you can use the `$_FILES` superglobal variable to handle file uploads sent via a form using the `multipart/form-data` enctype. Here's an example of how you can process form data containing file uploads in PHP:

```php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// Retrieve the uploaded file information
$file = $_FILES['file'];

// Check if the file was uploaded without any errors
if ($file['error'] === UPLOAD_ERR_OK) {
// Specify the directory where you want to save the uploaded files
$uploadDir = '/path/to/upload/directory/';

// Generate a unique filename for the uploaded file
$filename = uniqid() . '_' . $file['name'];

// Move the uploaded file to the specified directory
if (move_uploaded_file($file['tmp_name'], $uploadDir . $filename)) {
echo 'File uploaded successfully.';
} else {
echo 'Failed to move the uploaded file.';
}
} else {
echo 'Error uploading the file: ' . $file['error'];
}
}
```

In this example, we first check if the request method is `POST`. If it is, we retrieve the uploaded file information from the `$_FILES` superglobal using the input name `file`.

We then check if the file was uploaded without any errors by checking the `UPLOAD_ERR_OK` constant. If there were no errors, we specify the directory where we want to save the uploaded file (`$uploadDir`) and generate a unique filename for the uploaded file to avoid conflicts.

To move the uploaded file to the specified directory, we use the `move_uploaded_file` function, passing in the temporary file path (`$file['tmp_name']`) and the destination file path (`$uploadDir . $filename`). The `move_uploaded_file` function returns `true` if the file was moved successfully, and `false` otherwise.

Finally, we output a success message if the file was uploaded successfully or an error message if there was any issue with the upload process.
