PHP multidimensional array convert to forms

Question

Sorry for asking this idiot question, my head was blackout because of magento.

Here is the problem:

I have here an array:

array(2) {
  [0]=>
  array(3) {
    ["product_name"]=>
    string(12) "Test Product"
    ["product_qty"]=>
    string(6) "2.0000"
    ["product_price"]=>
    string(7) "15.0000"
  }
  [1]=>
  array(3) {
    ["product_name"]=>
    string(6) "Test 2"
    ["product_qty"]=>
    string(6) "3.0000"
    ["product_price"]=>
    string(7) "25.0000"
  }
}

How can I make transform this to:

<input type="hidden" name="product1" value="Test Product" />
<input type="hidden" name="amount1" value="2" />
<input type="hidden" name="qty1" value="15" />
<input type="hidden" name="product2" value="Test 2" />
<input type="hidden" name="amount2" value="3" />
<input type="hidden" name="qty2" value="25" />

Thanks for your answer.

Answer 1

Try this:

foreach($array as $pKey=>$product){
   foreach($product as $key=>$option){
       echo "<input type='hidden' name='{$key}_{$pKey}' value='$option'/>\n";
   }
}

It will give you a result like this:

<input type='hidden' name='product_name_0' value='Test Product'/>
<input type='hidden' name='product_qty_0' value='2.0000'/>
<input type='hidden' name='product_price_0' value='15.0000'/>
<input type='hidden' name='product_name_1' value='Test 2'/>
<input type='hidden' name='product_qty_1' value='3.0000'/>
<input type='hidden' name='product_price_1' value='25.0000'/>

Answer 2

foreach ($array as $i => $product) {
    foreach ($product as $key => $value) {
           $name = $key . $i;
           echo "<input type='hidden' name='$name' value='$value' />";
    }
}
