When you want to compare values in PHP then you can use either == or === operator. But these both operator are not same. It’s good to know the difference between them.
These both operators fall under the category of Comparison Operators. The first operator ‘==’ is known as Equal Operator in PHP and checks for the equal values and the second operator ‘===’ is known as Identical Operator and checks for equal values and it also checks that if both the values are of same variable type or not.
