associative array

[neubie]

how can i take an array like: array(1, 2, 3, 4)...
and format it to look like this: array(1=>2, 3=>4)?

 

[hmerrill]

$my_array = array ("1" => "2", "3" => "4"

echo("my_array[1] = $my_array[1]"

prints:
-----
my_array[1] = 2

But be careful with this - associative array elements can either be referenced(I think) by the string keys of the key/value pairs, or by relative positioning in the array. So when you say $my_array[1], are you looking for the value whose string key is 1, or the value of the 2nd element(using relative addressing, the 0 element would be the first, and the 1 element would be the second)?
