Bung saya mau mengedit Isi Session saya Bagaimana yah ???
Saya menggunakan Kode Dibawah Okeh Hanya saja Ketika Input Baru gagal terus

foreach($_SESSION['shop_cart'] as $k => $v) 
{
	if($_SESSION['shop_cart'][$k]['id'] == $prdId)
		{
			$_SESSION['shop_cart'][$k]['id'] = $newId;
			$_SESSION['shop_cart'][$k]['jumlah'] = $newHarga;
		}
	else
	{
	 $_SESSION['shop_cart'][]= array('id'=>$prdId,'harga'=>$prodharga,'qty'=>$jmlproduct,'name'=>$prodname);
                             
	}
}
