PHP - Associative Arrays
Drupal loves arrays. To maximize your Drupal coding, you need to understand arrays, specifically associative arrays.
A typical php array is coded like this:
|$LearnTheBlueDrop = array('website', 'drupal', 80, 'Gary Coleman');|
As you know, each memory slot in the array is accessed via a numeric index. If you were to print the value of the second index
You would get: drupal
But Drupal takes it to a whole new level. Drupal uses associative arrays. Associative arrays are the same as index arrays but they have a key pair. Using associative arrays, the index array from the first example would be rewritten like this:
$LearnTheBlueDrop = array (
Now if want to print or use a value in the keys, reference that key.
This would print: drupal
Note: the last element in your associative array must have a trailing comma!
If you want to add another element to your associative array, it is simple.
|$LearntheBlueDrop['carpet'] = 'green';|
This would add another element in the associative array with the key named carpet with a value of green.
