PHP与Python都是最好的语言

一：如果不想要emoji表情字符：（移除微信昵称中的emoji字符）

1：第一个方法

function removeEmoji($nickname) {

$clean_text = "";

// Match Emoticons
$regexEmoticons = '/[\x{1F600}-\x{1F64F}]/u';
$clean_text = preg_replace($regexEmoticons, '', $nickname);

// 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;

}

2：第二种方法

function filterEmoji($str)
{
$str = preg_replace_callback( '/./u',
function (array $match) {
return strlen($match[0]) >= 4 ? '' : $match[0];
},
$str);

return $str;
}
