我创建了连接四个表的db查询，并在codeigniter中的数组中返回以下结果。

我想使用client_id创建关联数组，因此我可以将客户端的信息分组并一起显示。这是为了生成收据。可以将相同的文档发送到不同的客户端，因此必须按客户端显示收据。
我试图创建一个foreach循环来重新组织数组。
答案 0 :(得分：1)
这会将结果分组到一个数组中，原始数组称为$ arr：
$result = array();
foreach( $arr['results'] as $v ) {
$result[$v->client_id][] = $v;
}
要获得单个客户端（$ client_id），所有结果都会像这样显示
foreach( $result[$client_id] as $res ) {
// Use the data
echo 'Slip: ' . $res->slip_id . "<br />\n"
. 'Title: ' . $res->dwg_title . "<br />\n";
}
要显示客户订购的所有内容，请执行以下操作：
foreach( $result as $client_id => $temp ) {
echo 'Client_id: ' . $client_id . "<br />\n";
foreach( $temp as $res ) {
// Use the data
echo 'Slip: ' . $res->slip_id . "<br />\n"
. 'Title: ' . $res->dwg_title . "<br />\n";
}
}
这是你问题的答案吗？
Edit2 $res是一个对象...
显示单个客户端的方法和显示所有客户端的方法！
