If it were c++,this can be achieved by template,but as we know PHP is written in c,how's this kind of data struct implemented without template?

    maybe its just me, but this question makes little sense. –  May 31 '11 at 04:20
  • php arrays can take any arbitrary content, a templated vector in c++ can only hold many objects of the same type (but you can create different vectors of course) – knittl May 31 '11 at 06:30

It's a hash table. For the implementation details, see

or in general
