What does "<>" mean in this PHP code?

Question

if ($varr <> '') {

}

I know boolean operators "||", "&&" "AND" "OR", but "<>", I am seeing for the first time.

Answer 1

"Not equal to," like SQL. Exactly the same operator as !=.

Answer 2

It means !=. And my answer has to be 30 characters long.
