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

if ($varr <> '') {开发者_开发知识库

}

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

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

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

I'm sure it's not equal to, I've always used != in php though :)

Not equal to.

It is a comparison operator.

It is "not equal to", exactly the same as != (i.e. type juggling is attempted if appropriate).

See the manual.
