Post Array into array array in php

Question

I want to put my post array into array array. I have the following form (this form is inside a foreach loop) which will post array data like the following:

<input type="hidden" name="cl[]" value="">
<input type="hidden" name="cd[]" value="">

and the post array contains when viewed in firebug:

cl[]    4
cl[]    4
cd[]    John
cd[]    Shaw

and I want these value in one single like below:

$allData = array(
    array(
        'cl' => 4,
        'cd' => 'John',
    ),
    array(
        'cl' => 4,
        'cd' => 'Shaw',
    )
);

Please help.

how are these input elements rendered? are they dynamic? (add new row button) or this structure is static? (html form is hardcoded) — Kevin

For easy access name the array (optional)

<input type="text" name="data[cl][]" />
<input type="text" name="data[cd][]" />
<input type="text" name="data[cl][]" />
<input type="text" name="data[cd][]" />

Loop with a double foreach:

foreach($_POST['data'] as $key => $row) {
        foreach($row as $subkey => $values) {
                $array[$subkey][$key]   =   $values;
            }
    }

 print_r($array); ?>

Gives you:

Array
(
    [0] => Array
        (
            [cl] => val1
            [cd] => val2
        )

    [1] => Array
        (
            [cl] => val3
            [cd] => val4
        )

)

$cl[] =   4;
$cl[]  =  4;
$cd[]   = 'John';
$cd[]    ='Shaw';
if (!empty($cl) && !empty($cd)) {
    $count = count($cl);
    for ($i = 0; $i < $count; $i++) {
        $newArr[] = array('c1' => $cl[$i], 'cd' => $cd[$i]);
    }
}
print_r($newArr);

for loop is faster than foreach which I have already used. I don't thing any modification is there to speed up.
