The more I'm using data classes in PHP the more I find myself writing _clear() functions to empty out the variables. I finally did some searching and found a starting point for a function that would do it for me without having to hard code in each of the variable names. I don't remember where this starting point came from, but it didn't work out of the box anyway.
function _clear()
{
$arr = get_object_vars($this);
foreach ($arr as $key => $value)
{
unset($this->$key);
}
}
