PHP Bug Type: Scripting Engine problem
Bug description: Calling static method from instance method results in invalid $this
Here is an example ...
<?php
class Foo
{
function Foo()
{
$this->class = 'foo';
}
function doCall()
{
return Bar::staticFunction();
}
};
class Bar
{
function staticFunction()
{
if ( isset( $this ) )
{
print 'This isset <br />';
print_r( $this );
}
else
{
print 'Call as a static <br />';
}
}
};
$foo =& new Foo();
$foo->doCall();
?>
Note an instance of Foo is calling a static method of Bar. Bar does a
test to see if $this is set. $this should not be set, since the method
was statically invoked. Unfortunately, $this is set and its the instance
of Foo that made the call to the static method of Bar.
This bug makes writing methods that work both as static methods and
instance methods virtually impossible. It is also extremely unsafe to
allow Bar to access the member variables of Foo.
