requinix Posted January 19, 2013 Share Posted January 19, 2013 You should probably fix it then. If you need more specific advice than that, give us more to go on than "it doesn't work". Quote Link to comment Share on other sites More sharing options...

Christian F. Posted January 19, 2013 Share Posted January 19, 2013 Check the output from the PHP script, to ensure that it only sends what you expect. Any other content, even a whitespace, will make the check fail. Quote Link to comment Share on other sites More sharing options...
trq Posted January 19, 2013 Share Posted January 19, 2013 And please, your code is NOT OOP. Quote Link to comment Share on other sites More sharing options...
cpd Posted January 19, 2013 Share Posted January 19, 2013 (edited) Not only is it not object oriented its illogical. It doesn't make sense: "class func extends connect"? What on earth is that meant to mean? When creating inheritance hierarchies it should be logical and you should consider the question "Is class A a class B" E.g. Is a Car a Vehicle? "class Car extends Vehicle". Edited January 19, 2013 by cpd Quote Link to comment Share on other sites More sharing options...
