What potential issues could arise when using file_put_contents and fopen in PHP to download files?

One potential issue that could arise when using file_put_contents and fopen in PHP to download files is the lack of error handling. If the file download fails for any reason, the script may not handle the error properly, leading to unexpected behavior or incomplete downloads. To solve this issue, you can use try-catch blocks to catch any exceptions that may occur during the file download process and handle them accordingly. 

try {
    $url = 'https://example.com/file.zip';
    $file = fopen($url, 'rb');
    if ($file) {
        file_put_contents('downloaded_file.zip', $file);
        fclose($file);
        echo 'File downloaded successfully.';
    } else {
        throw new Exception('Failed to open file for reading.');
    }
} catch (Exception $e) {
    echo 'Error downloading file: ' . $e->getMessage();
}
