why isn't this unsetting?
 
PHP Code:
        echo "<pre>";
        print_r($formdetails['taglist']);
        echo "</pre>";

        foreach ($formdetails['taglist'] AS $k)
        {
            if ($k == $tagtodelete)
            {
                echo $k . $tagtodelete;
                unset($formdetails['taglist'][$k]);
            }
        }
        echo "<pre>";
        print_r($formdetails['taglist']);
        echo "</pre>";
        die; 
Code:
Array
(
    [0] => admining
    [1] => amazon
    [2] => another tag
    [3] => ebs
    [4] => ex-girlfriend
    [5] => life
    [6] => meme
    [7] => music
    [8] => retest
    [9] => singledom
    [10] => test
    [11] => test again
    [12] => wishlist
    [13] => work
)

        print_r($formdetails['taglist']);
        echo "</pre>";

        foreach ($formdetails['taglist'] AS $k => $v)
        {
            if ($v == $tagtodelete)
            {
                echo $v . $tagtodelete;
                unset($formdetails['taglist'][$tagtodelete]);
            }

        print_r($formdetails['taglist']);
        echo "</pre>";
        die;

I THINK it should be :

Code:
echo "<pre>";
        print_r($formdetails['taglist']);
        echo "</pre>";

        foreach ($formdetails['taglist'] AS $k => $v)
        {
            if ($v == $tagtodelete)
            {
                echo $v . $tagtodelete;
                unset($formdetails['taglist'][$k]);
            }
        }
        echo "<pre>";
        print_r($formdetails['taglist']);
        echo "</pre>";
        die;

or an array flip will work if you just process the element value.

alternatively for anyone else baffled by this in the future (probably me).
PHP Code:
        $tagtodelete = urldecode($_POST['tagdelete']);

        $formdetails['taglist'] = explode(',', $formdetails['taglist']);

        unset($formdetails['taglist'][array_search($tagtodelete, $formdetails['taglist'])]);
        $formdetails['taglist'] = implode(',', array_values($formdetails['taglist']));
