在php中创建$ _POST数组中的变量

Question

I am having a $_POST array look like this:

Array
(
    [veryfy_doc_type] => Array
            (
                [0] => 1
                [1] => 2
            )

    [id_number] => Array
            (
                [0] => 3242424
                [1] => 4456889
            )

    [document_issuer] => Array
            (
                    [0] => 1
                    [1] => 3
            )

    [verify_doc_expiry_date] => Array
            (
                    [0] => 2016-01-26
                    [1] => 2015-02-20
            )

    [doc_id] => Array
            (
                    [0] => 15
                    [1] => 16
            )

    [user_id] => Array
            (
                    [0] => 14
                    [1] => 14
            )
)

Using this array I need to get each values into php variables.

I tried it something like this, but it doesn't work for me.

foreach($_POST AS $k => $v) { 
    //print_r($v); 
    list($doc_type, $id_number, $issuer, $expiry_date, $doc_id, $user_id) = $v;
}

echo "Type = $doc_type";

Can anybody tell me how to figure this out. Thank you.

So you want to reference each of the sub-array values while looping the main array... maybe something like this?

// Loop one of the sub arrays - you need to know how many times to loop!
foreach ($_POST['veryfy_doc_type'] as $key => $value) {
    // Filter the main array and use the $key (0 or 1) for the callback
    $rowValues = array_map(function($row) use ($key) {
        // Return the sub-array value using the $key (0 or 1) for this level
        return $row[$key];
    }, $_POST);

    print_r($rowValues);
}

This would get you structured arrays for each set of data.

From here I'd suggest you leave the arrays as they are rather than exporting to variables, but if you wanted to you you could use the list() as in your example.
