bit of an odd bug

Hi,

This looks a lot more like a limitation of the Zend engine to me. The
second observation you made is correct, at least, from my point of
view. You are literally calling a function named clamav::scanBuffer(),
not the member function of the class clamav.

Hope this helps,
Nicolas Bérard Nault.

Ok, I'm in need of a sanity check here.

step one:
$input = "foo";
$scanning_class = "clamav";
$result = $scanning_class::scanBuffer($input);
now this fails with a "Parse error: parse error, unexpected
T_PAAMAYIM_NEKUDOTAYIM"

So ok, you can't put variables at the front on a class call like that.
Minor bug I'm thinking at this point, but I wonder if I can work round
it. So, onto step two:
$input = "foo";
$scanning_class = "clamav";
$func = $scanning_class."::scanBuffer";
$result = $func($input);
Which fails with a "Fatal error: Call to undefined function
clamav::scanBuffer()"

Just doing:
$result = clamav::scanBuffer($input);
of course works absolutly fine.

Somebody just tell me that this isn't exactly expected behaviour and
it's a minor bug

this is all on 5.0.3 btw.

Cheers.

This is a known limitation. I suggest using the reflection classes to
work around this.

class foo {
static function bar() {
print "static method!\n";
}
}

$class = 'foo';
$method = 'bar';
$x = new ReflectionMethod($class, $method);
$x->invoke(NULL);

That, I'm afraid, is expected behavior, though I believe you can use:

call_user_func(array($scanning_class,'scanBuffer'));

http://www.php.net/call_user_func

I could be wrong though

Hi Gareth,

In addition to the other options people have mentioned, you could also
use the old standby of:
eval("$result = $scanning_class::scanBuffer($input);");
