Ask on their forums.

You could also join your local LUG, or a site like http://fsiu.uwc.ac.za
which is focused on PHP, Free Software and capacity building in Africa.
http://avoir.uwc.ac.za is similar, although tending more towards the
capacity and skills building side of things.
There are/should be mailing lists for most open projects that people
really don't mind you lurking on. Choose one and have some fun.

Hi,
I am having one doubt,i am using session variable for storing details.but
i am afraid if there is around 10000 users,wherether session will be able to
store all the datas of 10000 users,as i know abt session is that a temporary
file will be created in /tmp directory with session id name,i dont know how
much data that the session file will handle.

See your php.ini for setting the path to where you want session files
stored. I don't believe there's a limit to the size of your session
files, that said, there IS a limit as to how much memory PHP is allowed
to consume, and this obviously places an implicit limit on the size of
the session files.
Cheers,
Rob.

There could also be a limit on the number of files you can have per
directory..
Maybe it's better to use your own custom session handler and store
everything in a database.

Hello again,
I Use session_write_close() so the page loads quicker because i use
session on multiple place.
This because session has protection for race conditions.
Now it works very well and i don't have any problems at all.
I only see that there are multiple session cookie headers set.
I Personally think that one is enough :P.
How can i make it so that it just sets just one and not set this
header every time i call session_start or session_write_close.
Because i don't know when the cookie is set.
I think this will be an either/or situation.
Either it only sends one session cookie header and you don't use
session_write_close all over the place..
or, it sends multiple cookies and you do use session_write_close all
over the place.
The internals of php would set this behaviour, not something you can
change without changing the C code.
Hmmm...
I find it kinda strange that it sets the same uniqueId with the same
session name more then once.
It would be logical to just have one.. And overwrite the previous
session cookie.
Any other thing would be an programmers fault in my opinion.
Because you can't have more then one session id per session cookie name.
Also, the browser won't send all the cookies back.
This is just useless overhead.
But it seems that i have to live with it (for now).
I think ill report this as an bug to PHP.
Doubt you'll get very far.
I could open 10 tabs in firefox and I'll have the same session id in
each one, but they'll all be on different pages doing different things.
Even in IE, if I open a new page I'll get the same session id in both
browser windows.
That is a good thing.
But the problem is that there are like 5 or 6 headers for one request.

Hi,
could you check which encoding your script is saved with ?
I saw some strange things when printing some iso-8859 strings with a php
script
saved in utf-8.

Hi all ,
I am using php4.3.2,MYSQL and RedHat
I have a sql text as shown below:
SELECT
DISTINCT(tbl_chassis.serial_no),tbl_chassis.host_name,tbl_chassis.chasis_model,tbl_chassis.country,tbl_chassis.city,tbl_chassis.building,
tbl_chassis.other,tbl_chassis.status,tbl_chassis.chasis_eos,tbl_chassis.chasis_eol,tbl_chassis.chasis_user_field_1,tbl_chassis.chasis_user_field_2,tbl_chassis.chasis_user_field_3
from tbl_chassis tbl_chassis,tbl_card tbl_card
WHERE tbl_chassis.serial_no = tbl_card.serial_no
AND tbl_chassis.chasis_model LIKE '%WS-C5500%'
AND lower(country) = lower(trim('Malaysia'))
ORDER BY country,city,building,other
I need to extract the "tbl_chassis.chasis_model LIKE '%WS-C5500%'" and
"lower(country) = lower(trim('Malaysia'))" and join them to new string.
Anyone have any suggestion how to do this?
Thanks

I like this idea!
Do you expect them to be able to work with code written by others? If
so, hand them some of your existing code (good examples and not so good)
and ask them to figure out what it does and recommend changes.
I really really like the 'give them a problem and have them solve it'

To refine that a bit, you may want to give them some code that has
been intentionally broken (simple things for the entry level
position, such as missing semicolons or curly braces etc) and watch
to see how they go about discovering the parse errors. To me, it
would be better to hire someone that can solve problems quickly, not
someone who can simply tell you what a piece of code is doing. Just a
thought though - good luck!

We're looking to hire an entry level php programmer here, and I've

to see if I could find some tests that I could use. After clicking
thru many links, and finding mostly 'basic php tutorials', I've come
here to ask you people to do my homework for me. ;) Does anyone have
any links/resources for a basic php knowledge test? If not, I'll have
to write one from scratch myself, and mess up the rest of my day of
goofing off/sleeping.
What does $_POST['x'] mean?
What does $ in front of a string of chars without quotes mean?
That does register globals mean?
Is it possible to run php as a cgi script?
When it is necessary to use 'var' in php
code?
If you can't answer these questions how are you going to
know if someone is giving you the right answers?
There are tons of basic to advance books on the
commercial market about php.
I've gone the distance and shelled out literally 1,000 of
dollars buying books and hours learning the stuff. If you want answers
to your questions spend a little time so you will know if
someone has passed a test or not.
I've spent the past 8+ years 'going the distance' in PHP (quite a bit
longer when you count in things like Perl, PASCAL, COBOL, etc), and
shelled out about $25 on one PHP book. The web is a far better,
cheaper, and more up-to-date learning source. However, I'm a geek, not
some college kid who writes up documents so that HR can have a pretty
piece of paper saying this guy knows the difference between '==' and '==='.

Most definitely. This position isn't going to really require the person
to write their own apps. Most of the stuff he/she will be doing is
maintaining code already in place. Plenty of it will be my code, but
prior to me starting here three years ago, they used to just get people
on a contract basis, and there's some pretty messed up code. They even
contracted a job out to a couple of Russian programmers; code's pretty
clean, but all the comments are in Russian. ;) I like the idea of
giving them a piece of our existing code and getting them to do
something with it...I'll just have to get HR to accept my word on how
they did on it (they really want a question and answer sheet that they
can 'grade').
I really really like the 'give them a problem and have them solve it'
idea...
Yeah, one of my earliest thoughts on this was to have them write
something simple like connecting to a db, selecting multiple rows,
parsing our the result, and displaying it in some fashion.

I would probably agree that a problem would be better. Here's an idea,
have one of your HR people take some existing code and do something to
it to give it a bug, then have the guy fix it, and see how close he
comes to what's there.

Don't forget making it secure. Here is one of my questions people can use if
they like. Feel free to re-word it. I'm a programmer, not a writer ;)
What change(s) would you make to the following code to make it more secure?
$id = $_GET['id'];
mysql_query(“DELETE FROM myTbl WHERE id = $id”);
I like this question, because they have to know at least the fundamentals of
PHP security.

Believe it or not, I've lost count of how many times I've seen things
like this in Real Life. SQL Injection waiting to happen...

Agreed.
One thing I would add is to make sure they're familiar with the PHP
version you use.

Morning all,
I am looking to get the differnce in hours / minutes between 2 values.
Currently I have 2 time entries being retruned from mysql, one which is a
start time and
the other which is a finish time.
So
$start = '13:12:17';
$finish = '23:12:17';
How would one get the differnce between these 2 times??
I have looked at using the following but am not to sure....
function timeDiff($firstTime,$lastTime)
{
// convert to unix timestamps
$firstTime=strtotime($firstTime);
$lastTime=strtotime($lastTime);
// perform subtraction to get the difference (in seconds) between times
$timeDiff=$lastTime-$firstTime;
// return the difference
return $timeDiff;
}
//Usage :
echo timeDiff("$start","$finish");
Thanks
Chris

IMHO, the best is to generate a timestamp using mktime for each date.
you can the calculate the difference of timestamps and convert it back
using date.
$tm_start = mktime(substr($start,0,2),substr($start,3,2),
substr($start,5,2));
$tm_finish = mktime(substr($finish,0,2),substr($finish,3,2),
substr($finish,5,2));
$tm_diff = $tm_finish -tm_start;
print date("H:i",$tm_diff);
I don't know if date accepts negative timestamps, so be sure $finish is
later than $start
(you can also put the day in case $finish = "00:00:12" and $start
="15:00:00").
hope this'll help

function timeDiff($firstTime,$lastTime)
{
// convert to unix timestamps
$firstTime=strtotime($firstTime);
$lastTime=strtotime($lastTime);
// perform subtraction to get the difference (in seconds) between times
$timeDiff=$lastTime-$firstTime;
// return the difference
return $timeDiff;
}
//Usage :
echo timeDiff("$start","$finish");
Thanks
Chris

Morning all,
I am looking to get the differnce in hours / minutes between 2 values.
Currently I have 2 time entries being retruned from mysql, one which is a
start time and
the other which is a finish time.
So
$start = '13:12:17';
$finish = '23:12:17';
How would one get the differnce between these 2 times??

|Found this on the PHP web site,
you can add the conversions as the first lines in the functions.
function callDuration($dateTimeBegin,$dateTimeEnd) {
$dif=$dateTimeEnd - $dateTimeBegin;
$hours = floor($dif / 3600);
$temp_remainder = $dif - ($hours * 3600);
$minutes = floor($temp_remainder / 60);
$temp_remainder = $temp_remainder - ($minutes * 60);
$seconds = $temp_remainder;
// leading zero's - not bothered about hours
$min_lead=':';
if($minutes <=9)
$min_lead .= '0';
$sec_lead=':';
if($seconds <=9)
$sec_lead .= '0';
// difference/duration returned as Hours:Mins:Secs e.g. 01:29:32
return $hours.$min_lead.$minutes.$sec_lead.$seconds;
}

We have a site which requires users log in. Once they do so a session is
created (session_start), some data is saved as session data,
particularly data which identifies the user, their privileges, etc. If
the session ends, breaks, etc. The user must log in again.
There are also forms on the site. When a user submits a form, data, both
posted and session, is saved to a MySQL database.
If a session breaks when a user submits data via the form, the result is
that the user must log in again, the data is lost and the user unhappy.
This happens rarely - but when it does, it can upset the user who has
put effort into completing the form.
Is there a simple yet secure way of preventing this problem - for
example passing the session id with the form and resurrecting the
session if it has broken?
Thanks,
Jeff

To my knowledge, this particular behavior is by design. After the time limit
for a session has been reached, then the garbage collection will usually
clean it up. The only way to not break a session is to never clean up the
session files, or set the timeout to a day or so.
I wouldn't suggest sending the PHPSESSID via a form. That leads to people
being able to hijack sessions....
<from file='php.ini'>
; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
session.gc_maxlifetime = 1440
</from>

I'm looking for an opinion on programming style.
Basicaly, I make systems using PEAR::DB and PEAR::HTML_Template_IT. This
last one puts all the HTML away from the PHP code, which has made life
much easier.
Now, sometimes I warning messages like this one:
PHP Warning: Cannot modify header information - headers already sent in
I know what it means, so I just look for newlines at the end of my PHP
scripts, especially after the closing ?> and delete them.
Now, my question is: Is it a bad practice to "NOT" close the script with
the PHP closing "?>"? I mean, just leave the script without a closing PHP
simbols, as this scripts are included?

I never add the final closing '?>' in any script for this very reason.
whether it's bad practice or I don't know (can't be any worse than the
flamewar on internals@lists.php.net though ;-)

Some of the best coders are slackers... because they find better ways to
code to prevent having to write so much code :) But to answer the
question...

Best group member,
When a user does a specific action on domain1.com I want a cookie to be set
so that domain1.com and domain2.com can reach it. Ok, after reading the
manual for setcookie() I tried this:
setcookie("thevariable", "thevalue", time()+60*60*24*30, "/",
".domain1.com");
setcookie("thevariable", "thevalue", time()+60*60*24*30, "/",
".domain2.com");
However, I can not detect the cookie at domain2.com.
A solution would be to just make a redirect to the other domain where the
cookie is set and then return.
Question is: Can I not set a cookie at domain1.com to work at domain2.com?
Best regards,
Peter Lauri
