Subject: [PATCH] Fix issue #21.  (int)"is" is equal to zero

Faulty condition check only checks for string values.  In some cases, `$skey` is integer 0, and PHP converts the string `"is"` to integer 0 to do an integer conversion, causing this `if` check to fail.  Following code then dies due to faulty values used for offset.
