[FX.php List] "No Action Taken" on query

[Bob Patin]

Well… here’s what I’m doing—maybe you can tell me where my error is.

I have a page that checks all of my FM Servers to see that the WPE is up; it reloads the page every 4 minutes:

After my query I’m running this (I forget who gave this to me):

// is server up?
if( !fsockopen ($server, 80, $errno, $errstr, 2) ){
	// does a bunch of page formatting here for the display
}

I’ll try swapping that out for 

if (FX::isError($qResult)){
	// do stuff
}

So my question is this: if the WPE is down, FX isn’t going to return anything, is it? SO, assuming I just did a query, returning the results to $qResult, what do I look for to be returned when the WPE doesn’t respond? I always thought that, if WPE is down, nothing gets returned at all…

Last question: is there an advantage to using FX::isError() to something like this:

if ($qResult[‘errorCode'] != 0

? I think you told me once that FX::isError waits for the query to finish before it is invoked; wouldn’t that be the same thing with my little IF statement above? Is the first method better, or just simpler?

Thanks,

Bob

Additionally, I seem to recall that others on the list have posted methods that they use to check server health; could some of them chime in here?
