Official ZPE/YASS documentationAccess array elements
As of version 1.5.3 arrays including lists, associative arrays and strings can all be directly accessed using the square brackets notation. For example:
$a = [44, 32, 99] //Will print 44 print($a)
Previous versions of ZPE must use a function such as the
list_get_at_index or the
get chained function.
As well as this, it is also possible to go into an array of arrays (or list of lists) as of version 1.6.4. This is achieved due to multiple indexing:
$a = [[44, 32], [99, 23]] //Will print 32 print($a)
