Question

我正在尝试执行一项功能，即搜索多维数组中的值并将结果中的值相加。数组如下

    $arr = array (
        'MY106782'=> array ('code'=>"MY106782",'totalSales'=>"5625.00",'SponsorID'=>"MY246913"),
        'MY126192'=> array ('code'=>"MY126192",'totalSales'=>"5625.00",'SponsorID'=>"MY126637"),
        'MY128276'=> array ('code'=>"MY128276",'totalSales'=>"3180.00",'SponsorID'=>"MY106782"),
        'MY157278'=> array ('code'=>"MY157278",'totalSales'=>"5625.00",'SponsorID'=>"MY477500"),
        'MY167585'=> array ('code'=>"MY167585",'totalSales'=>"5625.00",'SponsorID'=>"MY106782")
    );

我试图搜索所有＆＃39; MY106782＆＃39;在＆＃34; SponsorID＆＃34;内数组，得到＆＃39; totalSales＆＃39;找到时的值，如果是多个记录，则添加值

非常感谢任何帮助。

Answer 1

尝试这样的事情

$i = 0;
foreach ($arr as $key => $value) {
        if ($value['SponsorID'] == 'MY106782') {
            $i++;
        }
 }

输出 2

由于您的数组是键值对数组，因此您必须确定要查找的键。检查一下：

$sponsor_id = "MY106782";
$total_sales = 0;
$arr = array (
    'MY106782'=> array ('code'=>"MY106782",'totalSales'=>"5625.00",'SponsorID'=>"MY246913"),
    'MY126192'=> array ('code'=>"MY126192",'totalSales'=>"5625.00",'SponsorID'=>"MY126637"),
    'MY128276'=> array ('code'=>"MY128276",'totalSales'=>"3180.00",'SponsorID'=>"MY106782"),
    'MY157278'=> array ('code'=>"MY157278",'totalSales'=>"5625.00",'SponsorID'=>"MY477500"),
    'MY167585'=> array ('code'=>"MY167585",'totalSales'=>"5625.00",'SponsorID'=>"MY106782")
);

foreach($arr as $values) {
    if($values["SponsorID"] == $sponsor_id) {
        $total_sales += (float)$values["totalSales"];
    }
}

echo $sponsor_id . " - " . $total_sales;

如果密钥在数组中只存在一次，则可以使用以下脚本。

 $arr = array (
    'MY106782'=> array ('code'=>"MY106782",'totalSales'=>"5625.00",'SponsorID'=>"MY246913"),
    'MY126192'=> array ('code'=>"MY126192",'totalSales'=>"5625.00",'SponsorID'=>"MY126637"),
    'MY128276'=> array ('code'=>"MY128276",'totalSales'=>"3180.00",'SponsorID'=>"MY106782"),
    'MY157278'=> array ('code'=>"MY157278",'totalSales'=>"5625.00",'SponsorID'=>"MY477500"),
    'MY167585'=> array ('code'=>"MY167585",'totalSales'=>"5625.00",'SponsorID'=>"MY106782")
    );
 $key_to_check = 'MY157278';
 if (array_key_exists($key_to_check, $arr)) {
    echo $arr[$key_to_check]['totalSales'];
 }else{
    echo "key not found."
 }
