php 如何用爬虫获取其他网站上 <script type="text/javascript">里

            var rqAry = [];
        filteAry = { date: [], league: [] };
        var htmlStr = "";
        for (var i = 0; i < curData.length; i++) {
            var tmpDate = curData[i][0].b_date;
            var weekObj = lotFunc.getWeek(tmpDate);
            filteAry.date.push(weekObj.cn);

</script>
curData 的值

如果curData在代码中, 用curl抓取网页, 然后正则匹配
如果curData是ajax读取的, 直接curl抓取ajax请求
