FOREACH function for dummies

Help jog this dummy's memory please :D

Code:

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) {}
