[RESOLVED] Interface problem

[Shawazi]

//file one
class Watcher implements watcherInterface {
	public function __construct($id) {
		//$this->initialize("watcherBasic", $id);
	}

public function createWatcher() {
	;
}
}

//file two
interface watcherInterface {
	abstract function createWatcher();
}

This is giving me the error:

Fatal error: Access type for interface method watcherInterface::createWatcher() must be omitted in /../.... Line 3

I'm staring at my PHP5 book and am using the same syntax.

As per www.php.net/interface, "All methods declared in an interface must be public, this is the nature of an interface."

After all, the error message says what the problem is. It's one of the better error messages that way:

"Access type for interface method ... must be omitted"

So, lose the "abstract". We know it's abstract. It's in an interface.

I ditched the abstract last night but was hoping there was some other answer. I should have known to look on php.net as opposed to this book that led me the wrong way. Books are overrated. php.net and phpbuilder.com are superior. 🙂

Books go out of date much more quickly. Still, personally I think you should be able to get away with adding an "abstract" attribute with no more than a Notice to the effect that it doesn't add anything.

At the same time, is possible to give an interface method a "static" attribute, so the 'no access type' restriction isn't completely true.
