var-name The name of the previous variable. If var-name is null, this function returns the name of the first HTTP variable.
This function iterates over the HTTP variables included within a request. Calling it with NULL causes it to return the name of the first variable. Subsequent variables are retrieved by passing the function the name of the previous variable. This function returns NULL when called with the name of the final variable.
Calling this function repeatedly returns all the variables exactly once, but not necessarily in the order in which they appear in the HTTP request. The variables url or url1, url2, …, url10 are included if URL PATH is set to ON or ELEMENTS, respectively.
