Php 多维数组输出。请帮我把这堆乱七八糟的东西取出来，循环一下

我有一个很棒的MySQL查询，它返回给我一个很棒的数组>

$join_sql = "SELECT $detail_table.`lead_id`, $detail_table.`field_number`, $detail_table.`value` FROM $lead_table JOIN $detail_table ON $lead_table.`id` = $detail_table.`lead_id` WHERE $lead_table.`date_created` BETWEEN '2012-03-18 00:00:00' AND '2012-03-19 23:59:59'";
$join_query = $wpdb->get_results($join_sql, ARRAY_A);

这将返回一个（我认为）复杂的关联数组，如下所示-

（我不了解数据存储方法，但对于我来说，将每一位数据都放在自己的维数组中，而不仅仅是每个记录的一行数据，这似乎太复杂了。但无论如何，这是我必须处理的。）

因此，这里有一个我需要获得的小样本>

[23] => Array ( [lead_id] => 3 [field_number] => 6.3 [value] => Jane )

因此，在我心目中代表“记录”的关键是[lead_id]。我需要能够创建一个var$first\u名称。我的结果集可能有50个唯一的[lead_id}，但对于名字，[field_number]将始终为“6.3”

那么，我如何循环使用pastebin并为每个元素创建变量，以便所有具有匹配编号的[lead_id]都输出类似的结果呢-

$first_name, $last_name, $whatev, $foo, $bar, $etc

我甚至不确定这是否有意义…：\

编辑：我想做的是访问“字段号”，它对应于字段的内容，即：名字、第二个名字等，以及相应的“值”，并按照与“lead_id”匹配的特定顺序输出所有这些内容。因此，[2]的所有lead_id将输出到CSV的一行中，然后输出下一个lead_id，等等

---

提前感谢！

鉴于您在

$xs

中的输入，以下内容：

$ret = array_reduce($xs, function($acc,$x) {
    $acc[$x['lead_id']][$x['field_number']] = $x['value'];
    return $acc;
}, array());

生成以下内容的输出：

array (
  2 => 
  array (
    1 => '37',
    2 => '051000549',
    3 => '1050000605321',

此外，您可能会发现

foreach

或

while

循环比

array\u reduce

更可读：

$ret = array();
foreach ($xs as $x) {
    $ret[$x['lead_id']][$x['field_number']] = $x['value'];
}

---

在

$xs

中输入以下内容：

$ret = array_reduce($xs, function($acc,$x) {
    $acc[$x['lead_id']][$x['field_number']] = $x['value'];
    return $acc;
}, array());

生成以下内容的输出：

array (
  2 => 
  array (
    1 => '37',
    2 => '051000549',
    3 => '1050000605321',
