It's always a matter of personal likes and dislikes. If you feel
comfortable with it, then stick to it (I do it sometimes, not always, as I
feel it's more important to try to hide stuff like private instance data
than to blindly adhere to rigid coding standards, as long as you can read
your code two months later)

That's how OO is meant to be. Do it this way, even if the language doesn't
enforce it. There's _really_ only a very small performance loss (approx.
0.01 msec per access). However take care - accessing _big_ data (like huge
arrays, for example) using access functions may instantly measurable
decrease performance, since variables are _copied_ unless you're using
references.

Why don't you do it?
class CSampleClass
{
var $m_a = 'value a';
var $m_b = 'value b';
function &Get($varname)
{
if (array_key_exists($varname,
get_class_vars(get_class($this))))
return $this->$varname;
// demo only
echo '[', get_class($this), "::Get: class variable doesn't
exist: $varname]";
return null;
}
function &Set($varname, $value)
{
if (array_key_exists($varname,
get_class_vars(get_class($this))))
$this->$varname = $value;
else
echo '[', get_class($this), "::Set: class variable
doesn't exist: $varname]";
}
}
$sc = new CSampleClass();
echo "m_a = ", $sc->Get('m_a'), ", m_b = ", $sc->Get('m_b'),
", other = ", $sc->Get('other'), "\n";
$sc->Set('m_a', 'new data for m_a');
$sc->Set('m_b', 'new data for m_b');
$sc->Set('other', 'new data for other');
echo "m_a = ", $sc->Get('m_a'), ", m_b = ", $sc->Get('m_b'),
", other = ", $sc->Get('other'), "\n";
