Yeah. But this feature of PHP is a boon if used carefully and a curse if careless. You can get AMAZING results if you're not careful to check the data types ;)

And that's why language like C# and java supports<> to restrict the type of data a collection can hold.

As a side point; I replicated a load of type safe collections etc for PHP (a good chunk of the java collections stuff) - If it's of use to anybody I can stick them in a google code project or suchlike. They'll obviously never be as fast as Java/C but they do allow for static typing of collections using primitive types or Classes. regards, Nathan

We don't want to decrease the performance, do we ? Best is to use the is_* functions :P -- Nilesh Govindarajan Site & Server Administrator www.itech7.com मेरा भारत महान ! मम भारत: महत्तम भवतु !
