how to reference value in array

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.

• Talus: Why the old PHP4 way to get through an array (with list + each) ? Even if for this problem, you should not even think about doing this kind of action
• Sackling: Can you please explain? This is not my code fully. What is the new way?
• Sackling: I should say, what is the php5 way of going through an array and why is this way so bad?
• Talus: You have to use the foreach keyword : foreach ($container as $key => $value) { /* actions */ } (one line here, because on a SO comment, you can't paste multi line code ;). It is a loop, when on each turn, $key will be the key of the current element (equivalent of the first argument of list), and $value its value (2nd argument).

Answer 1

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

• Sackling: This works so thank you! And now looking at it seams obvious. I thought the 115 and the [2] were connected. doh
