Multidimensional Array

If you can teach Multidimensional Array using $student['roll'], you know it. If you only know the heading, you don’t.

Do Multidimensional Array once by hand. ['name'=>'Asha','roll'=>12]. Change one input. Say the new result out loud.

Without Multidimensional Array, a class list gets messy and $student['roll'] is hard to trust.

Multidimensional Array shows up in a class list. Name $student['roll'], not “a real-world scenario”.

Don’t do this with Multidimensional Array: mixing 0-based and named keys blindly. Interviewers spot it in ten seconds.

After Multidimensional Array, Priya should still remember mixing 0-based and named keys blindly.

Close Multidimensional Array with: “If I skip it, $student['roll'] goes wrong like this: mixing 0-based and named keys blindly.”
