javascript - 如何在PHP中使用foreach只显示一次重复的数据？

Question

我想使用 PHP foreach 和 curl 从跨服务器中选择一些数据，并将其传递到表中。

我想查询每天两次抽奖的结果示例:来自

2015-12-08 13:00 和

2015-12-08 18:00我会将其显示为正确的图像 但我从这个函数得到的是这样的

public function getNumber() {

    $url = "http://103.5.126.24/PalmHallServer_kl/coodraw/coodraw!queryLuckNumberRecordByPeriods.action";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: Json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    $contents = curl_exec($ch);
    if($contents){
        echo $contents;
    }else{
        return FALSE;
    }
}

这是 Ajax

 $.get('<?PHP echo base_url('getnumber'); ?>', function (ldata, status) {

            var $json = $.parseJSON(ldata);
            $("#results").html("");

            var result = [];
            $.each(eval($json), function (i, val) {
                if (val.productName == 'DRAW1') {
                    result = val.luckNumber;
                }
                if (val.productName == 'DRAW2') {
                    result = val.luckNumber;
                }
                if (val.productName == 'DRAW3') {
                    result = val.luckNumber;
                }
                if (val.productName == 'DRAW4') {
                    result = val.luckNumber;
                }
                var table = '<td>' + result + '</td>';
                $(table).appendTo('#results');
            });
        });

这是后面的数据结果有很多，但我只选了一天您可以在此链接上看到

Answer 1

将 AJAX 代码更改为以下内容:

$("#results").html("");

var result = [];
var table = '';
tmpDRAW1 = '';
tmpDRAW2 = '';
tmpDRAW3 = '';
tmpDRAW4 = '';
tmpCounter = 0;

$.each(eval($json), function(i, val) {
  tmpOpenTime = val.lotteryOpenTime;

  if (val.productName == 'DRAW1') {
    tmpDRAW1 = val.luckNumber;
    tmpCounter++;
  }
  if (val.productName == 'DRAW2') {
    tmpDRAW2 = val.luckNumber;
    tmpCounter++;
  }
  if (val.productName == 'DRAW3') {
    tmpDRAW3 = val.luckNumber;
    tmpCounter++;
  }
  if (val.productName == 'DRAW4') {
    tmpDRAW4 = val.luckNumber;
    tmpCounter++;
  }

  if (tmpCounter == 4) {
    table += '<tr><td>' + tmpOpenTime + '</td>';
    table += '<td>' + tmpDRAW1 + '</td>';
    table += '<td>' + tmpDRAW2 + '</td>';
    table += '<td>' + tmpDRAW3 + '</td>';
    table += '<td>' + tmpDRAW4 + '</td></tr>';
    tmpCounter = 0;
  }

});
$(table).appendTo('#results');
});

这可以实现您想要的输出格式，并且不受 JSON 中 DRAW 排序的影响。
