爆炸并处理php动态数组

Question

I have a form that is built dynamically. Here's the form input

echo'<input class="input stickyinput" type="number"  name="'.$pestname['scoutlogpestname'].'#'.$obj['card_id'].'" >

The $pestname['scoutlogpestname'] can always be different. The $obj['card_id'] can be any value from 1-50. I placed the # in the name figuring I would need a delimiter to explode with. The array that prints looks like this. Numbers for any values entered and blank for any not entered.

Array
(
    [Aphids#1] => 11
    [Thrips#1] => 5
    [White-Fly#1] => 7
    [Aphids#2] => 
    [Thrips#2] => 1
    [White-Fly#2] => 22
    [Aphids#3] => 4
    [Thrips#3] => 1
    [White-Fly#3] => 
    etc....... possibly to 50
)

Can somebody please give me some insight on how to execute the explode loop so I can process the $pestname['scoutlogpestname'] and the $obj['card_id'] values? Thanks for looking.

Lose that weird hash thing and just use array notation in your form fields. For example...

<input name="<?= htmlspecialchars($pestname['scoutlogpestname']) ?>[<?= $obj['card_id'] ?>]" ...

This will produce something like

<input name="Aphids[1]" ...
<input name="Aphids[2]" ...

When submitted, this will give you an array of arrays in the $_POST super global, eg

Array
(
    [Aphids] => Array
        (
            [1] => 11
            [2] => 
        )
)

You can then iterate each entry and value array, eg

foreach ($_POST as $pestname => $values) {
    foreach ($values as $card_id => $value) {
        // code goes here
    }
}
