在PHP中循环使用多维数组

Question

So I have an Array set up as follows

Array
(
    [0] => App\Model\Entity\Member Object
        (
            [id] => 20
            [fname] => John
            // ...
            [member_attribute] => Cake\ORM\Entity Object
                (
                    [id] => 13
                    [membership_status] => Active
                    [last_payment] => 1541581496
                    // ...
                 )
)

I'm using a foreach loop for the first level

foreach ($aArray as $Member => $Value)

However I can't access the [member_attributes] data because it's in its own array.

Any help?

Answer 1

The items in your array are objects, so use object notation to access them:

foreach ($aArray as $Member => $Value) {
    $id = $Value->member_attribute->id;
}

There also is no need to use the key => value form of the foreach, you could just access your Members like:

foreach ($aArray as $Member) {
    $id = $Member->member_attribute->id;
}

That may be a matter of preference, however, I think it is more clear.
