I have seen that **int **and **integer **both are do the same job.There is "bool" and "boolean" too. As i know there is no wrapper classes in php like we have in java. So my question is, What is the exact purpose of having two kinds like this ?
Theoretically those are may be just two names for the same data types, But i wanna know the answer from you in your experience and your personal opinion on this. Thank you for your valuable time. Good day to you.
