[RESOLVED] Multi-Dimensional Arrays

[Slyke]

I'm basically trying to cycle though the first dimension of a multi-dimensional array. Please look at the code below:

<?php

$clientList['client1']['IP']="192.168.1.1";
$clientList['client1']['Name']="Client 1";
$clientList['client1']['URI']="client-1";

$clientList['client2']['IP']="192.168.1.2";
$clientList['client2']['Name']="Client 2";
$clientList['client2']['URI']="client-2";

$clientList['client3']['IP']="192.168.1.3";
$clientList['client3']['Name']="Client 3";
$clientList['client3']['URI']="client-3";

foreach ($clientList as $clientListIndex)
{
  echo $clientList[$clientListIndex]['Name'];
}

?>

I'm not sure how the syntax of this should be.

Figured it out, but not sure why it needs the "=> $clientListItem".

<?php

$clientList['client1']['IP']="192.168.1.1";
$clientList['client1']['Name']="Client 1";
$clientList['client1']['URI']="client-1";

$clientList['client2']['IP']="192.168.1.2";
$clientList['client2']['Name']="Client 2";
$clientList['client2']['URI']="client-2";

$clientList['client3']['IP']="192.168.1.3";
$clientList['client3']['Name']="Client 3";
$clientList['client3']['URI']="client-3";

foreach ($clientList as $clientListIndex => $clientListItem)
{
  echo $clientList[$clientListIndex]['Name'];
}

?>

because you're using a foreach loop, you can actually echo "name" with just $clientListItem['name']. the foreach construct works like this:

foreach($array as $value)

OR

foreach($array as $key => $value)

in your case, if you only defined $value, then $value would always be an array, and that wouldn't really help you at all! if you defined a key and value, then $key will be equal to
"client1" on the first iteration and $value will be equal to the 3 element array that you have for client1 (IP, Name, URI). hope that makes sense!

It does make sense since you explained it that way. I got confused with the => thing!
