This worked in PHP3:

if (isset($myobj->somefunction))
{ 
  $myobj->somefunction();
}

it no longer works in PHP4.

Please use function_exists instead
 [2000-07-05 20:22 UTC] ivo at ibuildings dot nl 
I tried like *everything* but I can't get function_exists() to work with classes.. only with regular functions.. or is there something special I should put in the function_exists parameter?

Ah, classes. Then use:
bool method_exists(object object, string method)
