php - 将 CSV 解析为多维数组

Question

我有一个 CSV 文件，其内容是：

jobname1, address11, address12, address13, date
item11, chilled, 2kg
item12, chilled, 20kg
jobname2, address21, address22, address23, date
item21, chilled, 2kg
item22, chilled, 20kg

如何在 PHP 中将其解析为多维数组，item11并将item12其附加到jobname1数组的位置和位置？同样的，我希望item21anditem22被追加到jobname2数组中。的输出var_dump应该是这样的：

array[0] = jobname1
           address11
           address12
           address13
           date
           item[0] = item11
                     chilled
                     2kg
           item[1] = item12
                     chilled
                     20kg
array[1] = jobname2
           address21
           address22
           address23
           date
           item[0] = item21
                     chilled
                     2kg
           item[1] = item22
                     chilled
                     20kg

你会使用这样的东西。

$fp = fopen("source.csv", "r");
$results  = array();
$curContext = null;

while ($rec = fgetcsv($fp)){
    switch (count($rec)){
         case 5:
             // header object
             if ($curContext){
                 $results[] = $curContext;
             }
             $curContext = $rec;
             $curContext["items"] = array();
             break;
         case 3:
             $curContext["items"][] = $rec;
             break;
    }
}
// push the last one onto the array
$results[] = $curContext;
