note 102659 added to function.key

while ($fruit_name = current($array)) {
    if ($fruit_name == 'apple') {
        echo key($array).'<br />';
    }
    next($array);
}

when submitting a form that has optional fields (input type=text left blank) the code above will fail on the comparison of "" stored in the variable. 

while ($key = key($array)) {
    $fruit_name = current($array);
   
    if ($fruit_name == 'apple') {
        echo $key.'<br />';
    }
    next($array);
}
