could you add a personalized color for the boolean variables?

does php support typed variables?

yes you're right; I make a new question:

could you add a personalized color for the boolean "values" (true/false up/lowercase)?

These words (true, false) are in the list of "reserved words" for PHP4 and PHP5 langs (see Tools->Settings->Reserved words).

I know true and false are in "reserved words"; but in other IDEs is possible to give them a different color (I like red for booleans).

then it would be nice to have two or say four sets of reserved words with possibilty to assign different colors to them , right?

yes... right
