public function removeEmoji($clean_text) { // 方法1：只取合法字符 preg_match_all("/[\x{4e00}-\x{9fa5}|0-9|a-z|A-Z|_]/u", $clean_text, $matches); $clean_text = isset($matches[0]) ? implode('', $matches[0]) : ''; // 方法2：去除表情字符，但测试过程中发现无法出去“国旗”表情 // Match Emoticons $regexEmoticons = '/[\x{1F600}-\x{1F64F}]/u'; $clean_text = preg_replace($regexEmoticons, '', $clean_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; }转载于:https://www.cnblogs.com/chenguoli/p/7607277.html
