Bug description: mysql_free_result does not free result for a referenced
result variable
Description:
------------
When I call mysql_free_result($Res) I expect I won't be able to use the
result in calls to mysql_fetch_array() etc. But if $Res is passed by
reference as a function parameter and is copied to another variable the
result is not freed and I can still use it.
I realize this is a VERY unlikely condition and I found it by accident
(mixed 2 lines of code and got surprised to see no error). Also this might
well be intentional behavior. Anyway, just in case.
Reproduce code:
---------------
a($Res);
function a(&$Res){
$Res=mysql_query("Show Tables"); $Res1=$Res;
mysql_free_result($Res);
mysql_fetch_array($Res); //still works!
}
Expected result:
----------------
Warning: mysql_fetch_array(): 7 is not a valid MySQL result resource in
Actual result:
--------------
No errors
