Question

我试图从csv中读取数组值并创建属于主键字段的子数组。例如，我说我有以下阵列结构＆amp;内容...

$events['venue-id'] = 55
$events['event-date'] = 19/02/13;
$events['event-name'] = 'Sports Day';

$events['venue-id'] = 76
$events['event-date'] = 22/02/13;
$events['event-name'] = 'Gala Event';

$events['venue-id'] = 55
$events['event-date'] = 29/03/13;
$events['event-name'] = 'Some Other Event';

使用venue-id作为父数组中的键的最佳方法是什么？将与其相关的其他数据分配给子数组？基本上是一对多的关系。

Answer 1

如果你愿意，你可以像这样构建它：

$events = array( 
  "55" => array(
    "event-date" => "19/02/03",
    "event-name" => "Sports Day"
   ),
  "76" => array(
   ...

);

这假设没有重复的场地ID。

Answer 2

试试这个：

$res              = array();
if (($handle      = fopen("your_file.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $res[$data[0]]['venue-id']         = $data[0];
        $res[$data[0]]['event-date']       = $data[1];
        $res[$data[0]]['event-name']       = $data[2];
    }
}

echo "<pre>";
print_r($res);

为重复键值创建多维数组
