What's the meaning of @var in php comments

Question

I see this (@var) in php comments a lot and have no clue what it means. Please tell.

// example.php (taken from yii framework application code)



        

Answer 1

They are PHPdoc comments and are generally used for IDE-typehinting/code completion (also sometimes documentation-generation, but not in this scenario). They have no relevance on the application itself and can be removed without incident.
