How do I add an associative array to an array of an array in PHP?

Question

I have an array called $hours, this array contains 24 other arrays each for the our of the day starting with 00

• $hours
  • [00]
  • [01]
  • [02]
  • [03]

How would I add a key value pair to the hours arrays so that my end result looks lik:

• $hours
  • [00]
    • key => value
    • key => value
  • [01]
  • [02]
  • [03]

Answer 1

You should try to use native PHP date datetime class

But if you really need to learn this,

To add a value in $hours at the index "00"

$hours['00']['key'] => $value

Where 'Key' is the key of your second node level array. By what you said I think you need a 3rd node level array.

So

$hours['00']['key'] => array('value 1','value 2');
