我有一个从SQL查询生成的数组：
<pre>
$df = $bdd->query('select * from V_Customer_Link where ref_customer in (select ref_customer from V_Customer_Link group by ref_customer having count(*) >=4)');
$result = $df->FetchAll();
$df->closeCursor();
</pre>
当我执行print_r（$ result）时，我得到了这个：
<pre>

如您所见，ref_customer只有2个不同。在未来，会有更多。
我想从这个数组中发送信息：
ALFKI：Rib，CarteIdentité，Kbis，Contrat
BOLID：Rib，CarteIdentité，Kbis，Contrat，Liasse fiscale
如果我做了一段时间或者一段时间，每次都会重复值ref_customer。
如何限制此值一次并获取所有其他值。
我希望我的描述足够清楚。
感谢。

我会根据ref_customer和implode值创建另一个数组。
未经测试，但这些内容
$ref_customers = array();
foreach($result as $r) {
$ref_customers[$r['ref_customer']][] = $r['TypeDeDoc'];
}
foreach($ref_customers as $ref => $typededoc) {
echo $ref . ' : ' . implode(", ", $typededoc);
}

您需要从基础数组中单独收集值。这可以通过迭代数组值并将它们存储在另一个数组中来完成。
你可以这样做（未经测试，但应该有效）：
$return = array();
foreach($result as $r) {
$key = $r['ref_customer'];
$return[$key][] = $r['TypeDeDoc'];
//// and even this would work:
// if (!array_key_exists($key, $return)) $return[$key] = array();
// array_push($return[$key], $r['TypeDeDoc']);
}
foreach($return as $k => $v) {
echo $k . ":" . implode(", ", $v);
}
答案 2 :(得分：0)
使用简单的foreach（）并根据需要组织数组。例如：
$newArray = array();
foreach ( $yourArray as $record )
{
$result = array_key_exists_r('ref_customer', $record); // use the function from the answer below
$document = $record['TypeDeDoc'];
$newArray[$result][] = $document;
}
您的新阵列将如下所示：
["Alfki"] => Array
(
[0] => "Carte identité"
[1] => "Contrat"
[2] => "Autre document"
)
以递归方式查找密钥
由于您实际上并不知道密钥的位置，因此需要使用递归函数。 this answer有一个很好的例子。
