Quick question: Is there a php function to turn an associative array into a bunch of request parameters?

Question

I have an array of the form array( 'paramName1'=>'param1', 'paramName2'=>'param2', ...) and want to turn it into a request string of the form paramName1=param1&paramName2=param2&...

It's easy enough to write a function to do this myself, but I was wondering if php already had a function to do this built in?

Answer 1

http_build_query

Answer 2

Yes, and that is http_build_query(). It's only available in PHP 5 though so if you're still using PHP 4 you'll have to roll your own function.
