if (1 == (int) true)
echo "this is true";
if (((boolean) -100 == true) && ((boolean) 1 ==true))
echo "yes, this is true";
if (1 == ((int)((boolean) -100)))
echo "Uhh... and this is also true. Does 1=100?";
Casting from boolean to integer we get 0 or 1, casting from any integer other than 0 to boolean, we
get "true". There is no right answer for question "is 1=true or not": so long
you gentelmen keep comparing dogs to cats, you may get odd and different results.
Right answer is, "thanks to automatic type juggling in php any number other than 0 or 0.0 and
any string other than "" is equal to true".
