I'm posting data from a web page to a php page with Ajax. It's working fine.

I get my data from the $_POST, loop through the values and create an array called checklist.

if($_POST != ''):
$dataset = $_POST['data'];
$checklist = array();
foreach ($dataset as $i => $row)
   $uid = $row['box-id'];
   $state = $row['box-state'] ;
   $eventid = $row['e_id'];
   $checklist[] = array('uid'=>$uid, 
                    'state'=> $state);

Checklist has two fields, a uid and a state.

I then run a script that generates another array, called $updates. It loops through a different set of objects and outputs the data to populate the variables for $updates. The structure of $updates is as such.

 $updates[] =  array('uid'=>$uid, 
                     'state'=> $state,
                     'class' => $class,
                     'container' => $button_cont,
                     'closer' => $button_closer);

What I would like to do is to compare $updates with $checklist.

I'd like to know the most efficient way to match the records by the uid and compare the state. If the state matches, I'd like to do nothing.

I've read a few of the articles on looping and search, but I'm thinking I've been looking at this for too long because it's Greek to me. Thanks for assistance.

    save the checklist like -

    $checklist[$uid] = $state;

    same for updates

    $updates[$uid] = array('state'=> $state,
                     'class' => $class,
                     'container' => $button_cont,
                     'closer' => $button_closer);

    then start the loop

    foreach ($updates as $key => $update) { 
       if ($update['state'] == $checklist[$key]) {
           //your action
       }//compare the values

    $key will be the uid.hope it will help you
