I somehow understand the differences between mysqli_fetch_row, mysqli_fetch_object, mysqli_fetch_assocand mysqli_fetch_array.
My question is, are they similar (if they are really almost the same as many say) that we should use? Why should we use the preferred option and is there a difference in performance?
I read that some people say that never use mysqli_fetch_array. I'm confused. I am currently reading several books on PHP, and all examples include it. If this is not the case, should I stop using it during exercise and use something else that you could explain and recommend?
I also read that they are equal:
mysqli_fetch_array( $result, MYSQLI_ASSOC ) = mysqli_fetch_assoc( $result )
mysqli_fetch_array( $result, MYSQLI_NUM ) = mysqli_fetch_row( $result )
mysqli_fetch_array ( $result ) = mysqli_fetch_assoc( $result ) + mysqli_fetch_row( $result )
If they are equal in concept, are there differences in performance? What should we use? Are differences for better performance for better programming skills that help developers share for easy work?
I read “ Head First PHP and MySQL (The Brain-Oriented Guide ” and “ QUICKPRO GUIDE PHP 5 ADVANCED VISUAL GUIDE .” They use different practices, but the authors do not explain anything about them.
I strongly believe that these differences have a big reason, and they have different uses and cases, but I cannot find where to use different functions and syntax.
Thank you in advance!
