Lars,
Thank you for your response. The function that raised this error is from
my own
extension module. I was not aware of phpinfo() and your suggestion to
run it helped
me resolve this issue. Turns out my CGI version is NOT using cgi/php.ini
but is using
apache2/php.ini instead.
Thanks again for your help--you deserve a raise. :-)

What would cause a difference of behavior in these 2 environments
with the php.ini
exactly the same in each directory??
I have a command line script that consequently uses the cli version.
This script works
just fine in that it can access API function in modules that are
loaded via cli/php.ini
However, when executing in the cgi environment, I get a "call to
undefined function" error
even though my 2 php.ini files are exactly the same.
Any idea what is causing this?
thanks,

Hi Andres,
When asking this kind of question, it would be very helpful if you
would tell us *which* function raised this error.
My first thought is that you tried to call a function which was
compiled in to the CLI version but not the CGI. What does phpinfo()
show when run under each?

I have an application developed that uses alot of PHP. Currently, it is
running on a Ubuntu 8.04 , single core CPU host. We are moving to a
quad core host for this application.
Is there anything special that I need to do to configure PHP to run on a
quad core host? I noticed that my current single core system has PHP
configured with Thread Safety disabled (as reported from phpinfo()).
Does that need to be enabled to run in a multi-core environment?
Any other suggestions for configuring PHP for multi-core use?
Thanks,
-Andres

You don't need to change anything.

interesting question.
i never paid any attention to the possibility of needing to make config
changes when moving from single to multi-core computers. i'm using apxs2 and
just assumed that there's no threading within each httpd process. in other
words, i assumed it's up to the os' scheduler to make something of the
hardware.
i'm curious to hear more on the topic.

Very interesting question indeed;
I moved from a single-core to dual-core some time back, and recently
moved from dual-core to quad-core. Never paid attention to the hyper-
threading difference in the httpd process. Would definitely be
interesting in seeing more information on this topic.

In regards to thread-safe compilations of PHP, if you don't absolutely
know you need it, you don't need it.
Utilizing a multiple CPU server setup with PHP depends on how you're
using PHP. If you're using FastCGI with a process pool, the number of
PHP processes is going to determine how many CPUs PHP uses, obviously
enough. On a quad core machine, 2 FastCGI children in the pool are
only ever going to use 2 cores, while 4 processes has a higher
likelihood of utilizing the entire set of CPUs. However, setting your
child process number too low can seriously impede your performance, so
there's some experimentation necessary to determine what's best for
your particular scenario, based on usage, server power, script
profiling, etc. but a good number to start with is (1.5 * # of logical
processors).
All of this necessarily changes if you're using Apache, of course.
Under the classic pre-fork model, Apache forks a new process to handle
a request every time the server is hit. So, to utilize four cores,
Apache would have to serve four pages simultaneously, forking four
child processes. Depending on your traffic and page generation time,
the amount of child Apache processes can pretty easily head up into
the hundreds, unless of course you have a lower MaxChildren set (which
I personally would recommend against because of Apache's huge glaring
vulnerability to SlowLoris). Under the worker model, Apache forks up
to X processes, and each process handles a configurable amount of
requests before dying, so like FastCGI, you'd have to configure the
number of children to be run, although it's recommended (I hear, I'm
not too very familiar with Apache) to use a much higher number than
the amount of cores, several dozen perhaps. Like I said, I'm not too
familiar with Apache, so I'd do some research and experimentation with
the number of child workers to give Apache.
I hope this helps :)

First we have people worrying about losing their jobs to kindergarten children,
now we
have people recommending giving Apache child workers. Call out the RSPCC!

Hi,
I have a problem with date function.
$gen_pos = mktime(0,0,1,10,25,2009);
$d1 = date("Y-m-d", $gen_pos); // 2009-10-25
$d2 = date("Y-m-d", $gen_pos + (1*24*60*60)); // 2009-10-25
$d3 = date("Y-m-d", $gen_pos + (2*24*60*60)); // 2009-10-26
$d4 = date("Y-m-d", $gen_pos + (3*24*60*60)); // 2009-10-27
$d5 = date("Y-m-d", $gen_pos + (4*24*60*60));
$d6 = date("Y-m-d", $gen_pos + (5*24*60*60));
$d7 = date("Y-m-d", $gen_pos + (6*24*60*60));
$d8 = date("Y-m-d", $gen_pos + (7*24*60*60));
line 2 and line 3 return same date,its wrong ... it should be 2009-10-25
, 2009-10-26 ? :)

Adding the number of seconds in a day could fall in the same day due
to daylight saving time, a more reliable way of adding one day (or a
given number of days) is this:
$tomorrow = mktime(0, 0, 0, date("m") , date("d")+1, date("Y"));
Then use date() with $tomorrow to format it.
(Taken from example #3 here:
http://www.php.net/manual/en/function.date.php, see the Note below the
example in that page).
Hope that helps.

Jonathan

strtotime would be a neater way of solving the problem...
ie (untested):
$n = 0;
while ($n <= 9)
{
$date = "d".$n;
$$date = date("Y-m-d", strtotime("+ $n days")
$n++;
}
If you are just enquiring about the maths though, I'm not sure!

Before most of you go on a rampage of how to please read below...
As most of you already know when using MySQL from the shell you can write your
queries in html format in an out file.
Example: shell>mysql -uyourmom -plovesme --html
This now will return all results in an html format from all queries.
Now I could “tee” this to a file and save the results returned if I so choose
to save the result of the display .
Let’s say I want to be lazy and write a php MySQL query to do the same so that
any result I queried for would return the html results in a table without
actually writing the table tags in the results.
Is there a mysql_connect or select_db or mysql_query tag option to do that
since mysql can display it from the shell?

echo "Select * from my_table" | mysql --html -ufoo -pfee database_name
However, this allows for your database password to be visible in the
process list for a brief moment of time. You might be better served by
finer grained process control where you can check the output and provide
input as needed. Or a simple expect script might suffice.

Rob.

Hi All,
Not sure of the best approach, need your feedback. I have 4 images on a
website. These are used in navigation. When I load a reference webpage on my
local machine the local page calls 4 images from an external website, each
image will be on a different domain.
What I want to see is if the navigation images/buttons can be loaded/displayed
in my browser. If they can, then I will display the images on my local page.
If the images cannot be loaded, then this indicates some connection issue and
the result will be some text like 'Site Offline'. So just by glancing at my
local machine reference page I can tell if one or more of the different sites
is or is not available.
So what is the best function to use?
if ( @file_get_contents( DOMAIN_PATH . "images/navigation/nav_globalissa.png"
)):
or ???
Please also cc [email protected]
Thanks for any helpful suggestions.

Shouldn't it be:
if ( @file_get_contents( DOMAIN_PATH .
"images/navigation/nav_globalissa.png", FILE_BINARY))

There is no best function as such. Everything depends upon your requirement.
You can also use fopen() to get the contents of the remote file and do some
error handling that if you get any content then display image else a message
etc..
