here's a heads up folks.
in the event that you want to check the result of a trim for being empty the following code fails::
$emptyvar = " ";
if ( empty(trim($emptyvar)) )
{
echo "It was empty";
}
this code works as expected::
$emptyvar = " ";
$check = trim($emptyvar);
if ( empty($check) )
{
echo "It was empty";
}
