second array level

[Reimar Bauer]

Dear all


How can I directly acces the second level of an array.

At the moment I am doing something like this.


$subset=$ini_ar ray["section"];
$number=$subset["number"];


I would like to increment number by 1 without storing the data in a
different variable.
($ini_array["section"])["number"]




Array
(
[section] => Array
(
[number] => 1
)


)

regards

Reimar

$ini_array["section"]["number"]++;

OR

++$ini_array["section"]["number"];

will do it.

see

http://www.php.net/manual/en/language.operators.increment.php

and

http://www.php.net/manual/en/language.types.array.php

see the third example of how to access an item from a multi-dimensional
array directly.
