Use get_class($this)
function Go()
{
if (!isset($this))
{
echo 'Called Statically<br />';
}
switch(get_class($this))
{ // note get_class is lowercase (which I think is a bug, but it hasn't
changed, so oh well)
'a' : echo 'Called Dynamically<br />';
'b' : echo 'Called Statically<br />';
}
}
or, is_a() to include descendants (PHP 4.2.0+ I think)
function Go()
{
if (!isset($this))
{
echo 'Called Statically<br />';
}
if (is_a($this,'a'))
{
echo 'Called Dynamically<br />';
} else
{
echo 'Called Statically<br />';
}
}
Incidentally, this ability to call other methods and operate on your own
variables is in my opinion the greatest feature of PHP along with
aggregation. It allows dynamic (runtime!) multiple inheritance, which is
essential for the new version of a complex data-access project I'm working
on constantly (http://calendar.chiaraquartet.net)
Take care,
Greg
