Step 5 - Multidimensional arrays


PHP Array tutorial


As each element value of the array can be any type it means that it can be other array as well. If an array element value is an other array then this is a multidimensional array. Of course the internal array values can be arrays as well and so on. You can define 10 dimensional (or more) array if you want.

Creating a multidimensional array is as almost simple as the normal array. Let's see an example:

Code:
  1. $myLists['colors'] = array("apple"=>"red",
  2. "grass"=>"green",
  3. "sky"=>"blue",
  4. "night"=>"black",
  5. "wall"=>"white");
  6. $myLists['cars'] = array("BMW"=>"M6",
  7. "Mercedes"=>"E 270 CDI",
  8. "Lexus"=>"IS 220d",
  9. "Mazda"=>"6",
  10. "Toyota"=>"Avensis");
To acces and display an element in the multidimensional array you just extend the key list as follows:
Code:
  1. echo $myLists['cars']['Toyota'];

Of course you can define normal, mixed and associative multidimensional arrays.

As last step I will show you some usefull array handling function on the next page.
