-
Arrays are a great way of storing variables that natural collect together, such as colours, days of the week, members of a team, or items in a shopping basket.
-
Multidimensional arrays allow you to store array within arrays to store very complex data in one convenient location.
-
Use the extract() function to pull all items out of an array and into the global scope, as it is faster and also easier to work with.
-
Cycle through your arrays using foreach() or similar means, as holes in your array can cause more simple loops to access empty values.
-
The var_dump() function is a great way to see what is inside your variables, whether they are arrays or not - make liberal use of it when debugging to save headaches!
