PHP方法处理微信昵称特殊符号过滤
我们在通过PHP获取微信昵称,并且存于数据库的时候,由于一些昵称带有特殊符号,所以存不进去,这时候我们可以通过下面的方式来处理。
方法二
- protected function removeEmoji($clean_text) {
- // 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;
- }
