count feature is used to display the count of
elements in an array, map or the length of a string. The
expression was added in ZPE 1.7.9.
Whilst it looks like a built-in function, it is actually not and the underlying implementation is very different. By having the a different implementation, it actually runs faster too.
To use it, write it like a function:
$a = count("Hello world") print($a) $b = count([1, 2, 3]) print($b) $c = count([1 => 2, 2 => 3, 3 => 4]) print($c)
