As PHP is loosely typed, the only real way around this is to specify a
return type in a PHPDoc block, then parse that using reflection to get
the @return parameter.
another option is to use something like haXe which is an ECMA style
typed language that compiles to multiple targets, one of which is PHP.
Regards!

is_quantum() is pretty useful as well, if you want to see if it's sort
of there and not at the same time. Probably turns into a cat in a box at
some point too, everything quantum has cats in...

So, should we add to the list:
is_schrodingers_cat_alive()
??

I think PHP would crash trying to return the boolean value from that
one!

Thanks all.
I rediscovered DIFF, compared the source for the first and second rendering.
Besides the unique variable names there was also the message ... which
contained imbedded single quote marks. When I changed them to imbedded
double quote marks the problem went away.

Unfortunately, you have to unsubscribe yourself. Make sure you
don't have any forwarders being sent to your email account, if you're
unable. Just send a blank email to
[email protected] or go to
http://php.net/mailinglists and enter your email address, select the
General mailing list, and click the Unsubscribe button.

Hello everyone,
I've just subscribed to the list, and I already have a question.
what I need to do is to send mail using sockets. Actually, the
built-in Mail() function is great and I wouldn't have to search for
something else if I didn't need more than one message to be sent at a
time. Say, I have ten or a hundred of users who want to receive a
notification about new blog entries. If I use the mail() function in
the loop, it will be performed too slow since it constantly opens and
closes the door, I mean, the SMTP connection.
Have you figured it out yet?
I have written a SMTP function a couple of years ago which will talk to
any SMTP server directly via socket. The only limitation I have noticed
is that it does not support encrypted logins but that can be added, I
just never bothered to do it.
So let me know if you still require it and I'll dig it out.

That guy's partial to JOE. Pffft. Real men use Vim. And Emacs is for

And yeah, for what it's worth, I've been running Linux since 1996.
And yeah, cats are smarter than dogs.

I found this code below online and I am trying to modify it for my
needs. I want to pass a YEAR (Int) to the stored procedure and have it
create all the day in that passed year. With one tweak, If the day is
Sunday the "sStatus" field will equal "Closed" ELSE "Open". All
attempts come up with ERRORS. Also, I would like the sdate field to be
a DATE result. Little help please? I appreciate it.
USE colombo;
-- this table will store dates sequence
CREATE TABLE seq_dates
(
sdate DATETIME NOT NULL,
sStatus VARCHAR NULL,
);
DROP PROCEDURE IF EXISTS colombo.sp_init_dates;
CREATE PROCEDURE colombo.sp_init_dates
(IN p_fdate DATETIME, IN p_tdate DATETIME)
BEGIN
DECLARE v_thedate DATETIME;
DECLARE v_Status VARCHAR;
TRUNCATE TABLE colombo.seq_dates;
SET v_thedate = p_fdate;
WHILE (v_thedate < p_tdate) DO
IF (DayName(v_theDate) = "Sunday" {
SET v_Status = "Closed";
}else{
SET v_Status = "Open";
} // I know this CODE is wrong
-- insert dates squence into seq_dates table
INSERT INTO seq_dates (sdate, sStatus)
VALUES (v_thedate, v_Status);

You could probably do something cunning with the library functions mktime(),
etc, but I
have two functions:
Abs_day ($date); which converts $date into an absolute day, with 1:1:1800 =
day 0
and
Ymd ($abs_day); which converts an absolute day back into Y:M:D
For your purpose there is a lot of redundancy, but between them these functions
provide
all the information you have asked for. Day zero was a Wednesday, so you can
readily work
out the DOW for any arbitrary day.
I have tested these functions up to 2500, but no obvious upper limit).
// Convert date YYYY:MM:DD into absolute day; 1:1:1800 = 0, Wednesday
function abs_day ($u)
{
$days = array
(0 => array(0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334, 365,
375),
( 1 => array(0, 31, 60, 91, 121, 152, 182, 213, 244, 274, 305, 335, 366,
375));
// 0 is normal year, 1 is leap year
$y = $u[0];
if (($y % 400) == 0) { $ly = 1; } // See if leap year
elseif (($y % 100) == 0) { $ly = 0; }
elseif (($y % 4) == 0) { $ly = 1; }
else { $ly = 0; }
$y -= 1800;
$c = (int) (($y - 0.99)/100);
$c = (int) ($c * 0.75 +0.3); // Fiddle factor for centuries (most are
not leap
years)
$abs_day = (int) (($y) * 365.25 - $c - 0.1);
$d = (int) $u[1];
$abs_day += $u[2]-1 + $days[$ly][$d];
return $abs_day;
}
// Converts abs day to YMD.
function ymd ($day)
{
//echo '<h5>Stdu_408: Day = '.$day.'</h5>';
$days = array
(0 => array(0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334, 365,
375),
( 1 => array(0, 31, 60, 91, 121, 152, 182, 213, 244, 274, 305, 335, 366,
375));
$u = false;
$c = (int)(($day + 0.6)/36524.25); // No of centuries
$ly = 0; if ((($c + 2) % 4) == 0) { $ly = 1; } // See if leap year
$d0 = $day - (int) ($c * 36524.25 + 0.3); // Calculate remaining
days
$yy = (int) (($d0 -$ly + 1.1)/365.25); // Calculate year
$d2 = $d0 +1 - (int) ($yy * 365.25 + $ly - 0.125); // & remaining days
(again!)
if ($yy != 0)
{
if (($yy % 4) == 0) { $ly = 1; } else { $ly = 0; } // See if
leap year
}
$u[0] = 100 * $c + $yy +1800; // Calc calendar year
$i = 1; $j = 0;
while ($d2 > $days[$ly][$i] && $i < 14) { $i++; } // and
month & day
$d2 -= $days[$ly][$i-1];
$u[1] = $i; $u[2] = $d2;
return $u;

and that is exactly Essers point. you use $_REQUEST and assume the data came
from either GET or POST ... I'd hazard a guess your apps never expect such
'mixed'
data to be coming via COOKIE ... so your app will work as 'advertised' but if
some
one happens to slip a cookie onto someone else machine whose name matches some
rather important GET/POST input then it's that user who potentially has just
suffered
a denial of service - and you'll get the blame for the fact things don't work
and
you'll probably never be able to work out that it's a rogue cookie on the
client putting
a spanner in the works. (imagine you have an 'id' parameter and I managed to
set a
cookie on your users' machine called 'id' with a value of 1 ... have fun with
that)
you should be as strict with exceptable input vectors as you are with
sanitisation
of the actual input.
use of $_REQUEST is rather lazy - if you want to except either POST or GET for
a given
input write a simple wrapper function for that specific requirement - this will
also
save you from unforeseen problems related to incorrect or changed values for the
request_order ini setting.
