Get next element in foreach loop

Question

I have a foreach loop and I want to see if there is a next element in the loop so I can compare the current element with the next. How can I do this? I\'ve read about the cu

You could get the keys of the array before the foreach, then use a counter to check the next element, something like:

//$arr is the array you wish to cycle through
$keys = array_keys($arr);
$num_keys = count($keys);
$i = 1;
foreach ($arr as $a)
{
    if ($i < $num_keys && $arr[$keys[$i]] == $a)
    {
        // we have a match
    }
    $i++;
}

This will work for both simple arrays, such as array(1,2,3), and keyed arrays such as array('first'=>1, 'second'=>2, 'thrid'=>3).
