p

9. Arrays
• Is a compound type
• Key => Value pair
• PHP Has a bunch of built in functions
– Count, asort, key_exists, in_array
– http://php.net/manual/en/ref.array.php
• You can loop through arrays with foreach
• Or use other control structure functions
• http://us2.php.net/manual/en/language.control-
structures.php

10. User Defined Functions
• You can make your own functions also!
• Anatomy of a user defined function:
– function – tells php you will be making a function
– Naming Convention – the name you give your
function
– Arguments - Any variable that you want your
function to know about.
– Inside {} you can have it return or run other built-
in functions on the variable that you passed into
it.

11. Objects!!!!
• Objects are what cool kids use
• An object is collection of variables and
functions.
• But in an object:
– variable = property
– function = method
– Properties can be private or public
– When you call an object its called instantiation
and anything inside the __contruct() will run.
