Arrays and Array-style COM properties
Many COM objects expose their properties as arrays, or using array-style access.
You can:
-
Access multi-dimensional arrays, or COM properties that require multiple parameters using PHP array syntax. You can also write or set properties using this technique.
-
Iterate SafeArrays ("true" arrays) using the foreach control structure. This works because SafeArrays include information about their size. If an array-style property implements IEnumVariant then you can also use foreach for that property too; take a look at For Each for more information on this topic.
