如何在数组中引用值

Question

I have an a value in an array that I am not sure how to reference.

If I show the array like this:

 while (list($option, $value) = each($this->contents[$products_id]['attributes'])) {
     print_r( $this->contents[$products_id]['attributes']); echo "<br/>";   
}

I get the following output:

Array ( [5] => 115 [2] => 17 ) 
Array ( [5] => 115 [2] => 17 ) 

The value that I need is the 17.

Answer 1

$this->contents[$products_id]['attributes'][2]
