Overwrite value of true or false in PHP

Hi, I noticed that the following returns a 1. echo (1<2) ? True : False I was under the impression that true/false are of type boolean and not int. But in php anything other than 0 translates to true, meaning a 1. What I am trying to achieve is for a 1 to be a 1 and a true or false to be a true and false respectively and I do not want to put quotes around the word true/false either because then it is no longer a boolean but string. Is it possible to overwrite php's true/false and declare them as boolean? You often see in C++, some use Define(). Thanks.
