_{Official ZPE/YASS documentation}Count

The ZPE count feature is used to display the count of elements in an array, map or the length of a string. The count 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.

Using count

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)
