Question

array(4) {
  [0]=> int(9)
  ["obj"]=> int(3569)
  ["gen"]=> int(0)
  [1]=> array(1) {
    [0]=> int(0)
  }
}

I am learning PHP and came upon this while using var_dump.

I understand that in this array there is 4 keys, 0 obj gen and 1, and in these keys the values are as such, the number 9, the integer 3569, the integer 0 but what does the last part mean??

[1]=> array(1) { [0]=> int(0) } 

If someone can help or link me to some learning material that would be much appreciated, thank you!

Answer 1

The key 1 contains a nested array with a key 0 that has value 0.
