FOREACH function for dummies

[cinq]

Help jog this dummy's memory please

Array
(
    [15] => Array
        (
            [0] => Array
                (
                    [id] => 2
                    [name] => Tim
                )

            [1] => Array
                (
                    [id] => 4
                    [name] => karl
                )
	}
    [18] => Array
        (
            [0] => Array
                (
                    [id] => 13
                    [name] => max
                )

	}
}

This is the array $guyscache
I want to find out the details of the first element of the main array ( [15] )
using a foreach statement, how would I do it ?

PHP Code:

foreach ($guyscache AS $first)
{
    foreach ($first AS $second)
        {
            $id=$second["id"];
                $name=$second["name"];
                echo $id.$name;
        }
} 


This basically will print out everyone on the list ( Tim, karl, max ).
However I only want (Tim and Karl printed).

How can I amend the above code ?
Thanks

foreach() will run through each option of the array (allthough I don't think it will go into subarrays...)

If you only want to fetch the data for tim and carl, you'd have to add an if{} statement to check if the arrays key is 15.

Or, in your example, just drop the first foreach and make the second into:

foreach($guyscache[15] AS $value) {}
