我正在尝试从数组父组索引之一或使用foreach循环的第一级"1006"，但没有太多运气。我可以在此处使用一些帮助，将子数据或子数据从给定的数组组中获取。
Array (
[1004] => Array (
[0] => Array ( [od_id] => 1004 [pd_id] => 42 [pd_name] => Red Hat )
[1] => Array ( [od_id] => 1004 [pd_id] => 33 [pd_name] => Green Hat )
[2] => Array ( [od_id] => 1004 [pd_id] => 44 [pd_name] => Blue Hat )
)
[1006] => Array (
[0] => Array ( [od_id] => 1006 [pd_id] => 33 [pd_name] => Green Hat )
[1] => Array ( [od_id] => 1006 [pd_id] => 44 [pd_name] => Blue Hat )
[2] => Array ( [od_id] => 1006 [pd_id] => 41 [pd_name] => Pink Hat )
)
[1007] => Array (
[0] => Array ( [od_id] => 1007 [pd_id] => 29 [pd_name] => Purple Hat )
[1] => Array ( [od_id] => 1007 [pd_id] => 24 [pd_name] => Orange Hat )
[2] => Array ( [od_id] => 1007 [pd_id] => 44 [pd_name] => Blue Hat )
)
)
我想你想要下面这样的东西：-
<?php
$s=array ( "1004" => array ( " 0" => array ( "od_id" => 1004 ,"pd_id"=> 42 ,"pd_name" => 'Red Hat' ) ,"1" => array ( "od_id" => 1004, "pd_id" => 33, "pd_name" => 'Green Hat' ),"2" => array ( "od_id" => 1004,"pd_id" => 44,"pd_name" => 'Blue Hat' )));
foreach($s as $a=>$b)
{
foreach($b as $c=>$d)
{
foreach($d as $e=>$f){
echo $f;
}
echo'<br>';
}
}
?>
不确定我是否完全理解您的问题，但是如果您只想从给定索引中读取所有值，则可以执行以下操作：
foreach ($array[1006] as $arr) {
foreach ($arr as $k=>$v) {
echo "$k: $v ; ";
}
echo "'n";
}
这将打印：
od_id: 1006 ; pd_id: 33 ; pd_name: Green Hat ;
od_id: 1006 ; pd_id: 44 ; pd_name: Blue Hat ;
...
