Pascal: how to declare number of dimensions of a dynamic array during runtime?

Question

我知道setlength（array，a，b ...）用于声明动态数组和维的长度，它需要您知道维数，因此如何声明n维（n是变量）？

Answer 1

This is not possible to vary the nesting level of normal (dynamic) arrays runtime.

But have a look at COM arrays, the vararray functions in unit variants though, afaik it is possible with those, but that is a purely library construct.

An example is at http:///www.stack.nl/~marcov/phpser.zip implementing a simple php array deserializer that decodes a nested structure.
