Question

I need to check array value, but when array is empty, I get this: Error: Cannot use string offset as an array

if (!empty($items[$i]['tickets']['ticket'][0]['price']['eur'])) {  //do something  }

How to do it correctly?

Answer 1

You need to check if the variable is set, then if it is an array and then check if the array’s element is set. The statements of the if will be executed in order and will break when one is false.

if(isset($items) && is_array($items) && isset($items[$i]['tickets']['ticket'][0]['price']['eur'])) {
    //jep it's there
}
