I need help how to do this I need to go through a column (amount) of the datagridview when the amount reaches 0 so that it does not let me insert products that do not exist and leave me a message that there is no stock (no products) Any ideas?...

I need to find out if the value of a key changes on the next round Ex: if($manzanas[$key]['cantidad'] == $manzanas[$key + 1]['cantidad']){ echo 'La cantidad de manzanas es la misma'; } else { echo 'La cantidad de manzanas cambio'; }...
