Re: [PHP] Please help with glob
Yesterday I yum installed these:
glibc-common.i386 2.3.4-2.54
glibc.i686 2.3.4-2.54
glibc-headers.i386 2.3.4-2.54
glibc-devel.i386 2.3.4-2.54
And about ten minutes ago I recompiled PHP with identical configure
options as before. And this time the glob function is inside PHP.
Phew.
Hopefully someone else will benefit from this post.

The format command returns different result if the 'U' for timestamp is specified. It also returns the same (wrong) result for DateTime::getTimestamp() as well. The clients are booking entry into a place at a specific time, for example 7am in Singapore on the 12 April. Clients can book right up to the entry time (if there is space available). I want to make sure they are not trying to book in the past. The booking system is in the UK but clients can book from anywhere. I cannot rely on them having the right time on their systems (or being in the right place). Plus this would mean relying on client supplied data, which is a no-no ;) I have previously used a gmt offset, which was good enough as there are not that many people who book close to the entry time. But now its time to improve this and use proper time zone info which can change without my input. If no-one can find a problem with my code I will submit it as a bug.

May I suggest including the timezone in your date format (O or e)? It may show
the two date strings to be equivalent.

Timestamps (the integer value) do not hold the timezone data.
Internally, the value represents a number of milliseconds from a point
in time.
So saying "timestamp for Asia/Singapore" isn't right. It is just "Timestamp".
The following script (http://pastebin.com/0MQAaYUq) may show you in a
more concrete way ...
new DateTimeZone('Asia/Singapore'),
'NewYork ' => new DateTimeZone('America/New_York'),
'London ' => new DateTimeZone('Europe/London'),
'UTC ' => new DateTimeZone('UTC'),
);
foreach($a_Times as $s_Time) {
echo 'Time : ', $s_Time, PHP_EOL;
// Create datetime objects
$a_DateTimes = array();
foreach($a_Timezones as $s_Timezone => $tz_Timezone) {
$a_DateTimes[$s_Timezone] = new DateTime($s_Time ,
$tz_Timezone);
}
// Print the date
foreach($a_DateTimes as $s_Timezone => $dt_DateTime) {
echo
'Current time in ', $s_Timezone, ' : ',
$dt_DateTime->format(DateTime::RSS),
' Offset : ', str_pad($dt_DateTime->getOffset(), 6, '
', STR_PAD_LEFT),
' Timestamp : ', ($i_Timestamp =
$dt_DateTime->getTimestamp()),
' Local : ', date(DateTime::RSS, $i_Timestamp),
PHP_EOL;
}
echo PHP_EOL;
}
?>
outputs (http://pastebin.com/mETSbR7h) ...

Getting the the timestamp for a DateTime object will return the
timestamp appropriately converted to the local timezone.
If you don't want to lose the timezone, then

Hi,
Found the problem:
Unix timestamps are a moment in time and so timezones have no influences
on them. They count the number of seconds since 1970-01-01 00:00 *UTC*
See: http://en.wikipedia.org/wiki/Unix_time
So the timestamp will always be the same no matter which timezone.
I will use by workaround to get the expected timestamp for use in
comparisons.
Regards
Ian

[PHP] Ranges for case statement and a WTF moment.
Hi. I just wanted to quickly see if PHP supported ranges in its switch/case statement (http://en.wikipedia.org/wiki/Ellipsis) Completely unexpectedly, the above code runs but produces the wrong output. Interestingly, altering the number of dots and adding spaces all result in parse errors ... case 0..9 : // 2 dots, no spaces case 0 .. 9 : // 2 dots, with spaces case 0 ... 9 : // 3 dots, with spaces It was confusing that the initial code ran without a parse error, but considering that it did, it would suggest that the case values are actually meaningful in some way. php -r "var_dump(10...19);" Interesting output ... string(6) "100.19" And that took me a little while to work out. It's all to do with PHP's type juggling. 10...19 What I'm not sure is why the middle empty string is output as 0. "10" . . ".19" becomes "10" . "0" . ".19" which becomes "100.19" Oddly, more . don't work. php -r "var_dump(1019);" all result in parse errors. I don't know if this is a "bug" per se, but it is an oddity that I though I'd share. And what is even more surprising is that the initial code works in the PHP V4.0.0. So maybe an 11 years old bug. You really would have thought I'd have more to do with my time!

Just tested PHP V3.0.11 and I get the same response.
Seems that this is just the way it is.
An oddity for since 1999-06-26 at least.
