Sorry: > > Fatal error: Cannot declare class _ASYNC_SAMPLER, because the name is > already in use in /path/lab_8/php/asyncSamplerClass.php on line 14 I found out why this is occurring. There is another instance of requiring the same source file in another class def constructor function. It is in the _CS_FIND class def. So the error is probably from this even though the _CS_FIND instance is created AFTER the call to require that is causing the error. JK
