How do I append a value to an array within an array in PHP?

Question

Given this PHP array:

$options['systems'] = array(1, 2, 3)

How would I append the value 4 to the $systems array within the $options array?

Have a look at http://php.net/manual/en/function.array-push.php and you'll figure something out. — Chris, Mar 10 '17 at 14:12
@AlexBlex They probably want to add it after the array is initialized. — John Conde, Mar 10 '17 at 14:15

You could use array_push to push additional items like so:

array_push($options['systems'], 4);

Or the shorthand version:

$options['systems'][] = 4;
