Kā (un kāds būtu labākais veids) no masīva string elementa izkasīt ārā itemid ciparu?
Array (
[currency] => LVL
[shipping] => 0
[tax] => 0
[taxRate] => 0
[itemCount] => 3
[item_name_1] => Preces nosaukums x
[item_quantity_1] => 1
[item_price_1] => 10
[item_options_1] => itemno: 14, itemid: 53, image: img/catalog/xxx/ico/14.jpg, key: 000014
[item_name_2] => Preces nosaukums y
[item_quantity_2] => 1
[item_price_2] => 10
[item_options_2] => itemno: 15, itemid: 54, image: img/catalog/xxx/ico/15.jpg, key: 000015
[item_name_3] => Preces nosaukums z
[item_quantity_3] => 1
[item_price_3] => 5
[item_options_3] => itemno: 2, itemid: 91, image: img/catalog/xxx/ico/2.jpg, key: A00002
)
