PHP를 사용하여 Instagram 댓글에서 이모티콘을 제거하는 방법은 무엇입니까?

<code class="php">public static function removeEmoji($text) {

    $clean_text = "";

    // Define regular expressions to target different emoji categories
    $regexEmoticons = '/[\x{1F600}-\x{1F64F}]/u';
    $regexSymbols = '/[\x{1F300}-\x{1F5FF}]/u';
    $regexTransport = '/[\x{1F680}-\x{1F6FF}]/u';
    $regexMisc = '/[\x{2600}-\x{26FF}]/u';
    $regexDingbats = '/[\x{2700}-\x{27BF}]/u';

    // Apply regular expressions and remove matched emojis from the text
    $clean_text = preg_replace($regexEmoticons, '', $text);
    $clean_text = preg_replace($regexSymbols, '', $clean_text);
    $clean_text = preg_replace($regexTransport, '', $clean_text);
    $clean_text = preg_replace($regexMisc, '', $clean_text);
    $clean_text = preg_replace($regexDingbats, '', $clean_text);

    return $clean_text;
