Question regarding the type of retcode.

I ran a curl command and $retcode returned 200.  I check against that variable if it's 200 or not.  I tried to check 200 as a string and integer but never matches so I ran these lines of code:

        xlog("L_INFO", "[$ci][$mi][CSeq $cs] Validating meeting ($rU).  Result: $var(result)  Return code: $retcode \n");

        if(is_int($retcode))

        {

                xlog("L_INFO", "[$ci][$mi][CSeq $cs] retcode is an integer \n");

        }

        if(typeof("$retcode", "str"))

        {

                xlog("L_INFO", "[$ci][$mi][CSeq $cs] retcode is a string \n");

        }

None of these xlog outputed.

How do I check for $retcode in if or switch statement?

Thanks
