http_build_query ignores the key if the value is an empty array. How is this not a bug?

Question

I ran into a problem today where I was passing a key with the value set to an empty array to http_build_query(). E.g.:

$args = array(\"foo\", \"bar\         


        

Answer 1

Can somebody explain to me why this is not a bug?

Technically, I don't think it should be labeled a bug. Rather, it's just how they designed the function to behave, whether others disagree with that decision or not.

Your API could just check with if (empty($_POST['2']))
