 'test');

echo (int) (7 > 5);     // Output: 1, ie: Calculates as true, outputs 1, 
                        // (int) doesn't do anything in
                        //  this scenario since true
                        // outputs as 1;

echo (int) (5 > 6);     // Output: 0, ie: Calculates as false, result is false, 
                        // (int) turns false into 0;

echo (int) ('CAT' > 'DOG');     // Output: false, The letter D 
        // is a higher value and C
echo (int) ('pig' > 'Pig');     // Output: true, The letter p 
        //is a higher ASCII value than P
