Is Memcached Running without Throwing Notice/Warning

After some experimenting trying to determine whether memcached is actually running it appears that the only way to do this is by creating a custom error handler to suppress the notice/warning thrown by Memcache::connect

I already have an error handler for my application that doesn't respond to this in a way that would suppress the error.

So if I have a method, say checkRunning() like so:

public function checkRunning() {
    $test = new Memcache;
    return @$test->connect(CACHE_HOSTNAME, CACHE_PORT);
}

How can I apply a custom error handler to this method so that it just returns false, without overriding my existing error handler?

Solution

  • I'm guessing your error handler is simply not written correctly. Take particular note of this:

    error_reporting() settings will have no effect and your error handler will be called regardless - however you are still able to read the current value of error_reporting and act appropriately. Of particular note is that this value will be 0 if the statement that caused the error was prepended by the @ error-control operator.

    If your error handler obeyed the @ operator, your code should be fine.
