Question

I have two arrays like this:

array1 
  2 => string '3' (length=1)
  3 => string '1' (length=1)
  5 => string '2' (length=1)
  6 => string '3' (length=1)
  4 => string '2' (length=1)

and

array2
  2 => string '1' (length=1)
  3 => string '1' (length=1)
  5 => string '1' (length=1)
  6 => string '2' (length=1)
  7 => string '1' (length=1)

I need to combine these two into one array. If the second array’s key is exist in first array keep second array’s values with the key.So result will be:

arrayResult
  2 => string '1' (length=1)
  3 => string '1' (length=1)
  5 => string '1' (length=1)
  6 => string '2' (length=1)
  7 => string '1' (length=1)
  4 => string '2' (length=1)

So how to combine these two array like above example?

Answer 1

Enter the array union operator:

$arrayResult = $array2 + $array1;
