Check for a change in variable value in forreach loop

Question

So I have a checkbox that sends to a PHP script. Basically, my checkboxes create an array, of course. Seeing it's one of those $var[] ones.

So basically, my array will look like this in code:

$vars = array('12345:0','45678:0','78910:0','3434:1','2345:1');

foreach ($vars as $var) {
    $vinfo = explode(":", $var);
    $vgroup = $vinfo[0];
    $vacct = $vinfo[1];

    // Various function calls with those variables. 
}

Now, as you can see. I am splitting for vinfo and vaccount. In my source. I have two accounts (in this example). Some groups belong to 0 and some groups belong to 1. I want to run the function switchAccount("details"); whenever there's a change in the $vacct variable in the foreach loop. In this case, it should only switch once (seeing 0 is default).

"Account" ($vacct) switches vary based on the user input in the checkbox. But (usually) always goes up one number. Again, depending on admin input.

Try this

$vars = array('12345:0','45678:0','78910:0','3434:1','2345:1');
$vacct = '';
foreach ($vars as $var)
{
    $vinfo = explode(":", $var);
    $vgroup = $vinfo[0];

    if($vacct != $vinfo[1])
    {
        switchAccount("details");
        $vacct = $vinfo[1];

    }
}
