The php.net website gives you a pretty good overview on possible comparison operators.

The operator "==" checks only the values if they are equal instead of having different types Like
if(True == 1) will return true by the operator "==" because True is Boolean and 1 is binary while True reefers to 1 in binary.

While "===" operator checks for the type also. Like
if(True === 1) will return false because both types are not same.

So use of operator == and === depends on the requirement basis.
