判断是否为utf8

if($this->is_utf8($userid)==1){
$userid = iconv("utf-8","GBK",$userid);
}

functionis_utf8($word)
{
    if (preg_match("/^([".chr(228)."-".chr(233)."]{1}[".chr(128)."-".chr(191)."]{1}[".chr(128)."-".chr(191)."]{1}){1}/",$word) == true || preg_match("/([".chr(228)."-".chr(233)."]{1}[".chr(128)."-".chr(191)."]{1}[".chr(128)."-".chr(191)."]{1}){1}$/",$word) == true || preg_match("/([".chr(228)."-".chr(233)."]{1}[".chr(128)."-".chr(191)."]{1}[".chr(128)."-".chr(191)."]{1}){2,}/",$word) == true)
    {
        return true;
    }
    else
    {
        return false;
    }

}

判断中文：

$str = "中文";
if (preg_match("/[\x7f-\xff]/", $str)) {
echo "含有中文";
}else{
echo "没有中文";
}
或
$pattern = '/[^\x00-\x80]/';
if(preg_match($pattern,$str)){
echo "含有中文";
}else{
echo "没有中文";
}
