if you are dealing with numbers that large, consider using some
arbitrary precision math functions that can work with as large of
numbers as you need.

OK, but with bigger numbers works fine again.
Right now I made a function to deal with this issue:
function remainder($dividend,$divisor){
$remainder= $dividend-(floor($dividend/$divisor)*$divisor);
return $remainder;
}
What do you think about it?

By the way it installed MySQL 6 and PHP 5.0.4 and from the console this
command does not work:
mysql -u root -p
but only this works:
mysql -h hostname -u root -p
I tried doing the same while connecting to the database via php but it
does not work.

Ok, I will show you two different ways to do this.
?php
$months = array(
'1' = 'January',
'2' = 'February',
'3' = 'March',
'4' = 'April',
'5' = 'May',
'6' = 'June',
'7' = 'July',
'8' = 'August',
'9' = 'September',
'10' = 'October',
'11' = 'November',
'12' = 'December',
);
foreach ( $months AS $i = $month ) {
$sel = ( $i == date('n') ? ' selected=selected' : '');
echo option value='{$month}' {$sel}{$month}/option\r\n;
}
?
Personally, I would do something like this.
?php
$options = array();
for ( $i=1; $i13; $i++ ) {
$month = date('F', mktime(0,0,0,$i,2,2000));
$sel = ( $i == date('n') ? ' selected=selected' : '');
$options[] = option value='{$month}' {$sel}{$month}/option;
}
$options_list = join(\r\n, $options);
echo select{$options_list}/select;
?
Now, if you are wanting to display the numerical month with leading
zero's, then you would want to look at the 'm' option for date() or
str_pad().
something like this might show you what you need.
?php
# str_pad test
echo str_pad(3, 2, '0', STR_PAD_LEFT)
?
Hope this helps understand a little more.

You could try having apache run as the UID of the user. With a few modifications to apache site config and you should be golden! HTH, Wolf -Original Message- From: admin [EMAIL PROTECTED] Sent: Sunday, May 11, 2008 1:06 AM To: php-general@lists.php.net Subject: [PHP] Safe mode story Hi all, I'm running a Plesk 8.3 mass hosting server equipped with PHP 5.1.6 on CentOS 5, and I'm facing the problem of PHP Safe mode barfing at the UID mismatch of PHP scripts uploaded by user's FTP UID, and later executed by Apache UID, where user's PHP scripts thusly uploaded attempt to write any files while doing their job. Is there an educated solution? What if I relax safe mode checks to gid (safe_mode_gid=On), and given that GID is psacln for every Plesk-hosted customer, with only UIDs being different, is there any risk that folks operating on their own chmod 660 files will be able to overwrite other people's chmod 660 files? Or will open_basedir be enough to prevent unwanted PHP level file access while relaxing safe mode uid check at the same time? (by default, it is properly set by Plesk in %mysite%/conf/httpd.include) ? BTW, safe_mode_exec_dir is empty by default, does it mean if I do set safe_mode_gid then users will be able to exec other Plesk users' cgi-bin scripts etc. because of GIDs being equal?? Safe mode has _got_ to be there for some good reason.

I put the SESSION variable into $cart $cart = $_SESSION['selection']; then I start the foreach and this is where I get messed up. I am trying to ECHO the following syntax to the screen with each selected product: The part I need help with is to write the foreach loop to give me $product (so I may query the database to find out the product name) and the $quantity (so I may show the user what they are purchasing). The part that is messing me up is that this is an array.

Re: [PHP] creating an xls file from mysql data
Hi,
You could always do this within mysql itself. You also have the wrong output
header and what seems to be some quite inefficient code, anyway take a look
at the following.
SELECT order_id,product_name,qty
FROM orders
INTO OUTFILE '/tmp/orders.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY ''
LINES TERMINATED BY '\n'
Thanks

[PHP] Re: How to determine if file is writable and deletable
I ended up using posix_access() which is what is_writeable() should be. is_writeable() is virtually useless. Al wrote: I need to determine if a file is truly deletable by a php script, Deleting permissions seem to be the same as writing, they probably have the same criteria. is_writable() seems to virtually useless in most cases. It doesn't take into account the directory ownership/permissions; which, best I can tell, is the real determining factor. I've resorted to having to determine the directory's ownership and then compare the directory's rights with the owner's and then the other ['world']. E.g., Assume my script was loaded with ftp, so it's ownership is the site-name, and I want the scrip to be able to determine if it can delete a file. Thus, the file in question must have its other permissions include write. Surely, there must be an easier way.

Re: [PHP] Help with a foreach statement
Hi Ron,
This code should work:
?php
$path_to_shopping_cart = './';
$iLength = count($cart);
foreach ($cart as $product_name = $quantity)
{
echo lia href=\ . $path_to_shopping_cart . product/ .
$cart[$product_id] . /\ . $product_name . /a - . $quantity .
/li\r\n;
}
?
Though I'm not sure about $cart[$product_id]. Where is that coming
from?. It makes no sense here. Perhaps you want to do a
tri-demensional array in $_session, so you will have a
dual-demesnional array in $cart.
Let me know,

I put the SESSION variable into $cart
$cart = $_SESSION['selection'];
then I start the foreach and this is where I get messed up. I am trying
to ECHO the following syntax to the screen with each selected product:
The part I need help with is to write the foreach loop to give me
$product (so I may query the database to find out the product name) and
the $quantity (so I may show the user what they are purchasing). The
part that is messing me up is that this is an array.
My ECHO statement should look like this:
echo lia href=\ . $path_to_shopping_cart . product/ .
$cart[$product_id] . /\ . $product_name . /a - . $quantity .
/li\r\n;

You've even had to resort to using classes and other strange stuff to program. Clearly signs of mental fatigue. :-) :o. I think mental fatigue might be evident by one not using it.

Re: [PHP] $_SESSION v. Cookies
I can't see PHP sessions slowing down your site by that amount. As someone said, it should be no more than a split second. If you are having that much of a problem with them, then I would say it is either your implementation, or another determining factor. I would not, personally, stray away from PHP's GC of sessions. I would imagine that any third-party concoction could not be any faster. I would however, check to see how long PHP takes to clean up defunct sessions, and also monitor how many sessions are lying around at any given time.

Probably because the maximum signed 32 bit integer value is
2,147,483,648
OK, but with bigger numbers works fine again.
Right now I made a function to deal with this issue:
function remainder($dividend,$divisor){
$remainder= $dividend-(floor($dividend/$divisor)*$divisor);
return $remainder;
}
What do you think about it?
That will convert the numbers to floating point, which will give you
round off error if the numbers get too big.

I've resorted to having to determine the directory's ownership and then compare the directory's rights with the owner's and then the other ['world'].

[PHP] mysql_pconnect issue
hi...
running into a problem that i can't seem to solve...
using mysql_pconnect() and i'm trying to figure out what parameters have to
be used in order to connect to a local mysql session, where mysql is
accessed using the defaults (ie, no user/passwd/hostIP)
i can connect via the cli, by doing mysql, which accesses the db app..
however, for the life of me, i can't figure out what attributes to use to
simply be able to access mysql from within a php app running on apache.
it appears that mysql_connect/pconnect requires an actual user/passwd/hostIP
in order to work.
using mysql_connect(,,) or mysql_connect('','',') returns an
error..
i've looked in the php.ini file and set everything (user/passwd/host) to
with no louck..
any pointers would be helpful. (i can easily access the mysql if i set up a
user (grant access.)
but for now, i'm curious as to how to access the default mysql setup...
thanks
peace

[PHP] Ignore Tags
Hello. I am writing a script that scans some content for email addresses and then encrypts them in a way to hide them from spam bots (For more information, http://mailhide.recaptcha.net/ ). The Regular Expressions work perfectly fine, I look for plain email addresses as well as hyperlink email addresses (a href=mailto:[EMAIL PROTECTED] and a href=[EMAIL PROTECTED]). I am nearly done writing the script, the last requested feature is to have some sort of tags or way of making it so that the emails within these tags don't get encrypted. So for example the email within [EMAIL PROTECTED]/nomailhide] won't get encrypted. I know how to scan for the nomailhide tags and get its contents, I just can't figure out how to make it so that the callbacks that encrypt the emails don't touch, or ignore, the emails within the nomailhide tags. Perhaps I'm over complicating things, but I've already asked people in regex and php IRC channels and they too can't figure it out. I've spent 5 hours or so on this one problem and I think my head's about to explode so I'm going to leave it for a while. I would REALLY appreciate it if anyone could please help me out with this in any way possible, I would really value your time. Please, someone, I'm so desperate. If my message isn't really descriptive or anything please let me know, it's just that I'm so sick and tired of all of this.

RE: [PHP] Re: Ignore Tags
I didn't check out your source, but in terms of a regex that only matches items not surrounded by some special tag, what about negative lookaheads and lookbehinds, like: (?!\[specialtag\])REST_OF_YOUR_REGEX(?!\[specialtag\]) I've not used them in PHP, but just a quick thought that might help.
