PHP의 Instagram 댓글에서 이모티콘 문자를 효율적으로 제거하는 방법은 무엇입니까?

<code class="php">public static function removeEmoji($string)
{
    // split the string into UTF8 char array
    // for loop inside char array
        // if char is emoji, remove it
    // endfor
    // return newstring
}</code>

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

    $clean_text = "";

    // Match Emoticons
    $regexEmoticons = '/[\x{1F600}-\x{1F64F}]/u';
    $clean_text = preg_replace($regexEmoticons, '', $text);
    
    // Match Miscellaneous Symbols and Pictographs
    $regexSymbols = '/[\x{1F300}-\x{1F5FF}]/u';
    $clean_text = preg_replace($regexSymbols, '', $clean_text);

    // Match Transport And Map Symbols
    $regexTransport = '/[\x{1F680}-\x{1F6FF}]/u';
    $clean_text = preg_replace($regexTransport, '', $clean_text);

    // Match Miscellaneous Symbols
    $regexMisc = '/[\x{2600}-\x{26FF}]/u';
    $clean_text = preg_replace($regexMisc, '', $clean_text);

    // Match Dingbats
    $regexDingbats = '/[\x{2700}-\x{27BF}]/u';
    $clean_text = preg_replace($regexDingbats, '', $clean_text);

    return $clean_text;
