$product[1]['name']='xxx'; $product[1]['height']='100'; $product[1]['qty']='2'; $product[1]['op'][0]='color'; $product[1]['op'][1]=size; $product[1]['opv'][0][0]='red'; $product[1]['opv'][0][1]='blue'; $product[1]['opv'][1][0]='xl'; $product[1]['opv'][1][1]='l'; $product[1]['opv'][1][2]='xxl'; $product[2]['name']='yyy'; $product[2]['height']='10'; $product[2]['qty']='2'; $product[2]['number']='2'; $product[2]['op'][0]='color'; $product[2]['op'][1]='weight'; $product[2]['opv'][0][0]='red'; $product[2]['opv'][0][1]='silver'; $product[2]['opv'][1][0]='90'; $product[2]['opv'][1][1]='60'; $product[2]['opv'][1][2]='42';   first .1 product nr. second .1 option nr. third .1 option value. 

$product = array(); foreach ($_post $key => $value) {     $key_array = explode('.', $key);     $name = array_shift($key_array);     $subscript = array_shift($key_array);     $target =& $product[$subscript][$name];     // if there remaining elements, they're subscripts nested array levels     foreach ($key_array $next_subscript) {         $target =& $target[$next_subscript];     }     $target = $value; }
