I believe you often see a comparison of some PHP applications, said to replace strlen () with Isset (), isset than strlen execution speed and so on.
Example:
if (Isset ($username [5])) {
The username is at least six characters long.
}
The reason is that isset is a language structure, and strlen is a function. What is the language structure? Is it different from the function?

Java has won the TIOBE Index programming Language Award of the year. This is because Java have the largest increase in popularity with one year time (+5.94%). Java leaves runner ups Visual Basic.NET (+1.51%) and Python (+1.24%) far behind. At first sight, it might seem surprising a old language like Java wins this award. Especially if-to-consideration that Java won the same award exactly ago. On second thou
