Thank you for all responses about this topic.

Hi, I believe you can detect via the browser settings which language the user is using and then display the correct page depending on this. The PHP.net web site itself does this in some form whether or not by my suggested method I do not know, but it uses some form of detection to direct the user to the appropriate mirror web site.

Re: [PHP] automatic responder
You just need to get the HTTP_ACCEPT_LANGUAGE environment variable and see the order of the prefered languages. After that, you see if you have a translation for the first language, if the site doesn't have it, try for the next language, and so on.

[PHP] Random number generation and phpBB search IDs
Hi, I'm currently experiencing a problem with a phpBB board that appears to be due to the way random number generation works in PHP. I have posted on serveral phpBB boards and have received no answers, so I think I need to understand how PHP is dealing with this in order to resolve it. phpBB generates a unique index for search results using the following code (in search.php): - 8 - Code - 8 - mt_srand ((double) microtime() * 100); $search_id = mt_rand(); - 8 - Code - 8 - The problem is that the seed is generated from the system clock, and if two people search at the exact same moment (or more strictly, if the mt_srand statements get executed at the exact same moment), the random number generation system is initialised with the same seed in each case, so both searches receive the same $search_id, resulting in a MySQL error due to non-unique index fields. Looking through the documentation for PHP, it seems that versions 4.2.0 do not require the use of mt_srand as they will seed themselves when required. I've had a look at the PHP source code, and from my limited understanding, the seed appears to be generated using a function in php_rand.h: - 8 - Code - 8 - #define GENERATE_SEED() ((long) (time(0) * getpid() * 100 * php_combined_lcg(TSRMLS_C))) - 8 - Code - 8 - So this is still based to some extent on the current system clock, and the php_combined_lcg function in lcg.c also appears to rely on the current system clock along with the current process/thread ID. There is also some code to ensure that seeding only occurs once. But is this once per thread? Once per process? Once per something-else? What I'm trying to find out is whether this new seeding system will produce the same 'random' number if two mt_rand() statements are executing concurrently. My guess is that they won't, but I don't understand the internals of PHP or Apache well enough to know if their use of threads and processes will ensure uniqueness. The problem is occuring with PHP 4.3.9 running under Apache 1.3.33 on Linux kernel 2.4.26 (on a fairly typical cPanel-based shared hosting box). Unfortunately due to the timing-based nature of the problem, it has proven very difficult to set up test cases. I'd be very grateful for any assistance.

RE: [PHP] Random number generation and phpBB search IDs
Use a database query to verify the random number has not been used before.
$number_checker = 1;
while ($number_checker != 0){
#insert your $random_number code
$query = SELECT COUNT(*) AS total FROM some_table WHERE
random_number_field = '$random_number';
$result = mysql_query($query);
$number_checker = mysql_result($result, 0, total);
}
If this is in fact a bug (not likely) and it gets past this too, then wow
start using auto increment or something?
Best,

Subject: [PHP] Random number generation and phpBB search IDs
Hi,
I'm currently experiencing a problem with a phpBB board that appears to
be due to the way random number generation works in PHP. I have posted
on serveral phpBB boards and have received no answers, so I think I need
to understand how PHP is dealing with this in order to resolve it.
phpBB generates a unique index for search results using the following
code (in search.php):
- 8 - Code - 8 -
mt_srand ((double) microtime() * 100);
$search_id = mt_rand();
- 8 - Code - 8 -
The problem is that the seed is generated from the system clock, and if
two people search at the exact same moment (or more strictly, if the
mt_srand statements get executed at the exact same moment), the random
number generation system is initialised with the same seed in each case,
so both searches receive the same $search_id, resulting in a MySQL error
due to non-unique index fields.
Looking through the documentation for PHP, it seems that versions
4.2.0 do not require the use of mt_srand as they will seed themselves
when required. I've had a look at the PHP source code, and from my
limited understanding, the seed appears to be generated using a function
in php_rand.h:
- 8 - Code - 8 -
#define GENERATE_SEED() ((long) (time(0) * getpid() * 100 *
php_combined_lcg(TSRMLS_C)))
- 8 - Code - 8 -
So this is still based to some extent on the current system clock, and
the php_combined_lcg function in lcg.c also appears to rely on the
current system clock along with the current process/thread ID.
There is also some code to ensure that seeding only occurs once. But is
this once per thread? Once per process? Once per something-else?
What I'm trying to find out is whether this new seeding system will
produce the same 'random' number if two mt_rand() statements are
executing concurrently. My guess is that they won't, but I don't
understand the internals of PHP or Apache well enough to know if their
use of threads and processes will ensure uniqueness.
The problem is occuring with PHP 4.3.9 running under Apache 1.3.33 on
Linux kernel 2.4.26 (on a fairly typical cPanel-based shared hosting
box). Unfortunately due to the timing-based nature of the problem, it
has proven very difficult to set up test cases.
I'd be very grateful for any assistance.
Gordon.

[PHP] Bad PHP error
Hi all,
I have tried the following script:
$val = 100;
if (is_int($val)) {
echo $val;
}
else {
echo $val is not an integer\n;
}
The answer is:
100 is not an integer.
Why does this happen? I use PHP 5.
Isn't PHP able to work with values like 10 billion?
Do I need to use a certain special class for dealing with big numbers? How
can I use that class?
Thank you.

When you're outputting it, PHP will convert it back to a string, using
the normal integer representation (which is stored aswell). So that
should be fine ;)

Re: [PHP] fedora core 3 mail() not working from web
Thanks Curt.
I decided after a while to chalk this up as incomplete installation of
Fedora Core 3, and just removed the Apache-PHP-MySQL RPMs and replaced them
with their sources. I compiled them and now everything works!
NOTE: Since re-installing those three fixed the problem, there was no issue
with Sendmail, probably just with PHP/Apache.

You're probably on the right track with this.
Check your php.ini settings for sendmail_path.
Also.. the default setting for sendmail_path is 'sendmail -t -i' so
if sendmail isn't in the path for your webuser then it wont get
executed. To fix this, specifiy in you php.ini with the
sendmail_path the absolute sendmail executable. ie:
sendmail_path = /usr/sbin/sendmail -t -i

The weirdest thing was that there was NO error message. Even though in the
php.ini, I set the error reporting to E_ALL, I got no warnings, notices, or
failures.
I removed the RPMs and compiled the sources and now they work... so I guess
the problem was due to a incomplete installation of those RPMs off the

[PHP] mysql query with exclude
Hey all,
Hope you all have fun this saturday evening :)
I'm sure i'm having fun except i'm kinda stuck...
Ok here goes...
I have 2 tables, one with the people online (chat_online):
session_id
activity
And a second one where i keep the conversations between people(chat):
user1_sessionid
user2_sessionid
chat_conv
To see what chatter are still online during the last 2 minutes i do a
check like this on the chat_online table:
$limit_time= time()-130;
$sqlchatonline=select * from chat_online where UNIX_TIMESTAMP(activity)
=$limit_time;
ok, on my page i also do a query to see what conversations are going on
with the user:
$thisuser=session_id();
$getchatlist=select * from chat where (user1_sessionid=$thisuser) or
(user2_sessionid=$thisuser);
This selects all the conversations which this user has been/or is into.
I list all the chatpartners of thisuser.
Off course it is possible that other chatters who had a conversation
with this user are not online anymore.
So i need to combine those two queries in a way...
this is what i think it should be:
$getchatlist=select * from chat where (user1_sessionid=$thisuser) or
(user2_sessionid=$thisuser);
$resultchatlist=mysql_query($getchatlist);
while ($row=mysql_fetch_array($resultchatlist)) {
get the second chattersessionid in each conversation and check
if this chatter was still online in the last two minutes.
if he is not, exclude him from the array and do not show him in
the list (optional delete the record in the database)
}
or maybe i can combine those two queries in one?
Can someone help me out on this?
Thx in advance,
Reinhart

It seems that finally I will need to divide the numbers with 100, make the calculations that way, and specify that the numbers are in millions, because I can't find any solution with PHP. Yes, this is also a solution. bcmath functions are not good, because they need a string to work for, and not a number, and if I want to make some calculations, the numbers will be converted to numbers and... You have to use bc* functions for all calculations. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Re: Bad PHP error
Hi, I also use Win 2k with PHP 5 in command line mode. It is pretty strange that in an older version of Jaws it works better. Or... could I make some settings to make it work like in your case?

Re: [PHP] mysql query with exclude
Sounds like you need a join. Maybe something like:
select * from chat c1,
chat_online c2
where
UNIX_TIMESTAMP(c2.activity)=$limit_time and
c2.session_id = $thisuser and
((c1.user1_sessionid = $thisuser) or
c1.user2_sessionid = $thisuser));
Respectfully,

Hey all,
Hope you all have fun this saturday evening :)
I'm sure i'm having fun except i'm kinda stuck...
Ok here goes...
I have 2 tables, one with the people online (chat_online):
session_id
activity
And a second one where i keep the conversations between people(chat):
user1_sessionid
user2_sessionid
chat_conv
To see what chatter are still online during the last 2 minutes i do a
check like this on the chat_online table:
$limit_time= time()-130;
$sqlchatonline=select * from chat_online where UNIX_TIMESTAMP(activity)
=$limit_time;
ok, on my page i also do a query to see what conversations are going on
with the user:
$thisuser=session_id();
$getchatlist=select * from chat where (user1_sessionid=$thisuser) or
(user2_sessionid=$thisuser);
This selects all the conversations which this user has been/or is into.
I list all the chatpartners of thisuser.
Off course it is possible that other chatters who had a conversation
with this user are not online anymore.
So i need to combine those two queries in a way...
this is what i think it should be:
$getchatlist=select * from chat where (user1_sessionid=$thisuser) or
(user2_sessionid=$thisuser);
$resultchatlist=mysql_query($getchatlist);
while ($row=mysql_fetch_array($resultchatlist)) {
get the second chattersessionid in each conversation and check
if this chatter was still online in the last two minutes.
if he is not, exclude him from the array and do not show him in
the list (optional delete the record in the database)
}
or maybe i can combine those two queries in one?
Can someone help me out on this?
Thx in advance,
Reinhart
