I'm converting upper case characters in a string to lower case and am

As I've done a million times before with other non-numerical strings.
$thisStr = "CL22";
$strLow = strtolower($thisStr);
echo $thisStr;
Why does $strLow come up empty?
Because you're echoing out the original (uppercase) string. Try:
echo $strLow;

he should still see something.
the op should see the original string 'CL22'. Last time I looked strtolower()
did not modify the input as a reference.
So echo $thisStr; should result in the op seeing CL22
Unless there are other things happening that only the force knows about...
