Details
Removes a query type resource (i5_query or i5_execute) from memory
i5_free_query needs only to be called if you fear that your script requires too much memory, when a request returns very large results or if a large requests number are processed and may overload the web server memory. Its use is recommended as cleaner.
All memory resources required by a script are freed as the script ended.
Example
$sql = "SELECT * FROM BIGTABLE";
$query = i5_query($sql);
...
$res = i5_free_query($query);
