Thanks for the hints guys, but it was the wrong direction ... piwik is an analytics package ... google analytics with steroids ;) But the code base is a bit difficult to work with when one does not use frameworks like Zend. The starting point was a segfault in PHP which needs to be fixed, but we normally manage to avoid hitting it by managing things better. The updates I'd added to the Firebird driver in Zend were missing some checks which kicked it out at which point ... NOTHING gets logged.

2012/3/12 Lester Caine les...@lsces.co.uk:
More irritating is
'Notice: Array to string conversion' which are coming up all over the place.
I can understand what the problem is ... but trying to remove the notices is
more challenging ...
$secondsGap[] = array($gap[0] * 60, $gap[1] * 60);
if( isset($secondsGap[1]) ) {
$gapName = $secondsGap[0].to.$secondsGap[1];
} else {
$gapName = $secondsGap[0];
}
$secondsGap[] is two numbers, which are used to create the name string, so
what is the 'official' way of making this work without generating warnings?
Hi, Lester
I suggest that all done with this variable before is not of interest ...
Assuming this, I'd say the following:
$secondsGap[] = array($gap[0] * 60, $gap[1] * 60);
Implicit initializing of an array that has the following structure:
array( array(int, int) );
if( isset($secondsGap[1]) ) {
Trying to get the second element .. which will never happen if you
haven't added an element before the snipped you pasted here.
$gapName = $secondsGap[0].to.$secondsGap[1];
} else {
$gapName = $secondsGap[0];
}
[some-code]
I'm quite unsure what you want to do here. If you'd update the first
line as following it would always trigger the first condition:
$secondsGap = array($gap[0] * 60, $gap[1] * 60);
Bye
Simon

OK $gap comes from the loop
foreach(self::$timeGap as $gap)
self::$timeGap is a list of pairs of numbers.

What this code is doing perfectly in PHP5.3 is generating the text string to
display for each time period listed in the array of pairs of numbers ( some with
a 'blank' second number and what the code returns is a string of the format
'(number1)to(number2)' or simply '(number1)' - something fairly standard in PHP?
But the nanny message says it need to be re-writen, the question is 'How?' :(

You are understanding it correctly, the only thing that's missing is the population. The variables are defined (set), but not all are populated. $GLOBALS is a superglobal, you're right; globals set from userland scripts are not superglobals, but do wind up in the $GLOBALS array. Thus, all superglobals are globals, but not all globals are superglobals. -- /Daniel P.

That's because you're requesting day 0 of some month, which refers to
the last day in the previous month.
Try: $days_in_month = date('t', mktime(0, 0, 0, $next_month, 1, $year));

I got that.
Beating the same dead horse again, I think day 0 of this month should contain
the days in this month, but I am in the minority on this.

I think a lot of the confusion is that we're so used to array indexes
beginning at 0 that we tend to assume other things should start there
too. I found this confusing when I first came across the date stuff in
PHP. Now I'm used to it, it makes sense.

Tim:
I read somewhere that using:
global $x;
is not recommended. Whereas, it is recommended to use:
$x = $GLOBALS['x'];
echo $x;
In any event, what I found interesting is:
print_r($GLOBALS)
if will list all the variables (plus more) in your script. Thus, all variables
in your main script are also included in the $GLOBALS array.

Re: [PHP] questions about $_SERVER
The purpose of the global statement within a function is to let PHP know that the usage of a var name INSIDE that function is not meant to create a NEW variable, but instead, to reference the other (global) variable being used (and perhaps already defined) in your main script. Basically it works like this: You can: - create vars in the main script usable in that script's main body outside of any functions - create vars to be used entirely and only within any functions in your script; -reference vars from the main script within a specific function by referencing them with a global $xxx,$yyy,$zzz statement at the top of your function; And Finally You Can: - create $_SESSION['xxx'] var that can be seen anywhere in your application(s) during the life of the current session. Close the browser or fail to do a session_start() in a script and you can't see them, but who would do that? I'm sure someone will have something else to add, but I think this is all the knowledge one needs to accomplish most php programming. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Tedd,
That may well be, although as I write I can't recollect having seen that
anywhere; so I don't use that form. However I have been caught by something
like the following:
?php
function yes ($a)
{
global $x;
if ($a) $x = yes\n;
}
first (true);
echo $x;
?
but I haven't looked into $GLOBALS enough to know whether using them instead
would have saved my bacon.
