How many name-value pairs

[Anon]

Is there any way in PHP, like in Perl, find out how many name-value pairs there is? If there is such a way, what is it. Just give me a basic idea, no need to write out all the code.

Thanks,

P.S. I need this to limit the number of repetitions in a for loop.

For GET method check QUERY_STRING variable. Split it's value by ampersand signs. The size of the array you'll get as the result is the number of value-pairs.
Another way... check the size of HTTP_POST_VARS (or HTTP_GET_VARS for that matter). Not sure how they will work with arrays, though...
