Hi Alex,

Best way to describe a key and value is in an associative array. Like in Aleanas class, where she described an ice cream list.

$iceCream = array (

‘James’ => ‘I like strawberry icecream’, ‘Jim’ => ‘I like raspberry icecream’, );

Where the names are is the key, which if we want to use the key to be called into a table then we can just define $iceCream[‘James’], this will then bring back my name and my favourite iceCream as the value. You can see this if we use a var_dump($iceCream); you will be able to see the key and value.

A key I would class as the identifier, and value is the content of the key.

Arrays always start from 0 as the first key and then increments the second element as 1, then 2 and so forth.

Hope this has provided you with an example and an idea.

Kind regards, James Sorry for any typos, on my phone typing this.
