解决utf8编码的php生成csv打开乱码的问题

<?php
$arrTitle = array(‘第一列‘, ‘第二列‘, ‘第三列‘, ‘第四列‘, ‘第五列‘, ‘第六列‘);
$arrValue[0] = array(‘1‘, ‘2"*x,x‘, "t‘,3", ‘4‘, ‘5‘, ‘6‘);
$arrValue[1] = array(‘1‘, ‘2"*x,x‘, "t‘,3", ‘4‘, ‘5‘, ‘6‘);
$path = ‘./tttnew2.csv‘;
//如果默认编码不是utf8,先用函数utf8_encode将所需写入的数据变成UTF编码格式。
//$msg = utf8_encode($msg);
//$msg = iconv(‘gbk‘, ‘utf-8‘, $msg);
// 有bom的情况下"\xEF\xBB\xBF"第一次写入这段字符不可缺少
// 为了解决csv数据格式问题，每个格子用双引号那个包含，每个值中的双引号用%22替换
$strBOMHEAD = "\xEF\xBB\xBF";
$fp = @fopen($path, ‘a‘);
@fwrite($fp, $strBOMHEAD);
//开始写csv
@fwrite($fp, implode(‘,‘, $arrTitle) . "\r\n");
foreach ($arrValue as $k => $val) {
    foreach ($val as $kkey => $vval) {
        $val[$kkey] = str_replace(‘"‘,‘%22‘,$vval);
    }
        $strTmp = ‘"‘.implode(‘","‘, $val).‘"‘;
    @fwrite($fp,  $strTmp. "\r\n");
}
@fclose($fp);
