Do you need to know if it's capitalized, or do you just want to make it
capitalized if it isn't?
If you just want to make sure text is capitalized, you can use the
uc() function, or use \U and \E to bracket text.
eg.
$foo = "bar";
uc($foo);
# $foo is now: "BAR"
or
$foo = "bar";
$uc_foo = "\U$foo\E";
# $uc_foo is now: "BAR";
in the latter example, \U starts the capitalization, and \E ends it.
