How about a filename based upon a user id and the time the file was
uploaded. Unless you have multiple instances of the same user then it will
not be possible for the same user to upload a file at exactly the same time
as himself.
Just a thought...

I agree with this solution, though it only effects the OP if he is using a

Oh and generating random filenames from md5(), crossing your fingers and hoping
you've got a unique filename is better?
Or assume that files don't already exist in the directory?
You are going against convential wisdom about ensuring unique filenames.

There is no need to involve a math heavy modulus function just to
alternate row colours! The following single line will do it just as
well, swap the colours for whatever you need and echo them where
required:
$bgcolor = ($bgcolor === '#daf2ff' ? '#c9e1ef' : '#daf2ff');
Best regards,

It does not involve heavy math to color every other line. I use this
line when looping and determining if the background should be colored
or not:
<?php
if (($i % 2) == 0) echo ' style="background: #A8B1E9;"';
?>
Obviously, the first part is the important part. Good luck!

I've used the mod (%) function to do this, which also gives you the flexibility
of defining how many lines to alternate the colors or do whatever you need to
do every "X" lines.
Another method (and forgive me if this was mentioned, I didn't see it yet) is
to use a bitwise NOT to flip-flop a value. I think I did something like this
before:
$bgcolors[0] = "#FFFFFF";
$bgcolors[1] = "#000000";
$a = 0;
echo '<table>\n';
for ($i = 0; $i <= 100; $i++) {
$a = ~$a
echo '<tr><td bgcolor=' . $bgcolors[$a] . '>Some text</td></tr>\n';
}
echo '</table>\n';
Maybe it was 0 and -1 instead of 0 and 1.. I forget. But you get the idea.
The $a = ~$a flips the value of $a back and forth. You only have two options
but that maybe all you need.
And hey.. I've been known to do some goofy things so if there's some major
drawback to this in processing time or if I'm just stupid in some way, that's
cool.. feel free to speak up. But it does present another way to do what was
requested and the theory might help someone at least :)

SourceLabs released its AMP Stack and associated test data this morning.
Please forgive the (debatable) spam in advance; this post does contain
pointers to useful test information for capacity planners who are building
out AMP infrastructure for demanding deployments and others who are working
with PHP.
Consisting of pre-configured versions of Apache, MySQL and PHP, the
SourceLabs AMP Stack provides documented test results to give customers a
higher level of confidence in the reliability, scalability and security of
AMP than has been available to date. The stack is available free of charge
from our website at www.sourcelabs.com/AMPstack.htm.
This initial release of the stack has been tested per three of the Seven
CERT7 dependability criteria: unit testing, security hardening and
scalability. CERT7 augments the testing approaches that are typical of open
source projects by adding tests that focus on the performance, stability and
scale characteristics of integrated systems. Not only is this the first time
that an integrated open source stack has been tested this way, this is the
first time the results of the tests and the tests themselves (provided
through GPL) have been made publicly available. While many enterprise
software vendors do this kind of testing, they don't open the process for
customer review. We think that open testing is a big part of the future of
open source, and we're looking forward to the community taking our testing
harness and adapting it to their needs.
Some highlights of our findings from the test process:
. We performed a 72 hour burn-in acceptance test utilizing a subset of
the CERT7 scalability tests, resulting in 70-100% CPU utilization on a 2 CPU
Hyper-threaded machine, confirming the absence of detectable memory leaks
for these scenarios.
. Over 7,000 individual security checks were performed, showing that a
number of potential security vulnerabilities exist in default configurations
of components of the AMP stack. We configured the AMP Stack to protect
against these vulnerabilities.
CERT7 Scalability tests were performed in three areas: Static HTML,
Computational PHP and Database scalability, resulting in scale-out and
configuration recommendations for AMP deployments. Key findings include:
. Apache Web Server scalability was limited by bandwidth in all cases
tested, and not CPU or memory capacity.
. PHP processing scaled linearly with respect to CPU capacity. For
capacity planning purposes, this means that the desired number of servers
running Apache Web Server/PHP for a given application can be calculated
based on the processing speed of an individual user scenario. For this, an
understanding of the processing speed, the number of concurrent users, and
the desired user experience/response time would be used.
. MySQL scalability was limited by memory. For capacity planning
purposes, MySQL implementations should be optimized for the greatest
available memory rather than adding CPU capacity.
Complete Test results are at
http://www.sourcelabs.com/SourceLabsApacheMySQLPHPTestResults.pdf
To promote the new stack we are also announcing a maven contest in our
forums. Users that download our AMP stack and provide feedback, make clever
puns, ask or answer questions in our forum qualify for the grand prize: A
100 Watt Marshall Guitar Amplifier and a Fender Stratocaster Electric
Guitar. Just like the SourceLabs AMP stack, this is the kit that will let
you "go to 11". Each Friday afternoon for eleven weeks we will be giving
away a weekly prize consisting of an Ipod Shuffle and a DVD copy of "This is
Spinal Tap", culminating in the announcement of our grand prize winner on
June 10, 2005. Complete rules will be found at
www.sourcelabs.com/mavencontest.htm

Not debatable at all. An unrequested solicitation such as this is, on a
list such as this, regarded as spam. I am sure that several would like
to see something like [ANNOUNCEMENT] in the subject line...at least that
way everyone knows that there is no request for help and can choose to
skip over it should they desire.

I try to use both types of quotes in the proper circumstance. Having
said that, I came to computing in the age where we worried over CPU
cycles, but I don't see how in this day and age the difference between
the two would even matter. Even on a high load site the difference
between the two would be negligible.

Well....i have a 30k script, with double i get 8 or 9 seconds, with
sigle i get 0.05 or 0.08 seconds. The script basically made a lot of
querys, its part of a user manager module of a system im writing.
Remember, the hole world is not US or EU....i live in argentina and my
web server is a PIII 550Mhz 128mb and if you count that almost the
half of the people got a 56k dialup connection....I think that in some
cases it does make difference.

I agree it's going to be negligible, but even so the difference does
exist. The real question is which is faster between:
include "path/$file"
and
include 'path/' . $file
Can the compiler handle the in-line variables quicker than string
concatenation? It'll take a C guru who knows the PHP code well to
answer this fully.
Best regards,
Richard Davey

Because I'm bored, I decided to test the theory.
AMD 3200xp
1.5gb Memory
RHEL AS 3
I ran the test 20 times, and 18 of those times, double quotes were
faster than single quotes. Don't always trust what you read. Not to
mention the fact that the 'faster' of the two was 'faster' by an average
of less than .003 seconds to include 1000 files.
<?php
function microtime_float() {
list ( $usec, $sec ) = explode ( " ", microtime() );
return ( ( float ) $usec + ( float ) $sec );
}
for ( $i = 0; $i < 1000; $i++ ) {
$fp = fopen ( "file_" . $i . ".php", "w" );
fwrite ( $fp, "<?php\n\n\n?>" );
fclose ( $fp );
}
$single_start = microtime_float();
for ( $i = 0; $i < 1000; $i++ ) {
include ( 'file_' . $i . '.php' );
}
$single_end = microtime_float();
$double_start = microtime_float();
for ( $i = 0; $i < 1000; $i++ ) {
include ( "file_" . $i . ".php" );
}
$double_end = microtime_float();
$single = $single_end - $single_start;
$double = $double_end - $double_start;
echo ( "Single Quotes : " . $single . " seconds.<br />\n" );
echo ( "Double Quotes : " . $double . " seconds.<br /><br />\n" );
if ( $double > $single ) {
$time = $double - $single;
echo ( "Single Quotes are " . $time . " seconds faster than double
quotes." );
} else {
$time = $single - $double;
echo ( "Double Quotes are " . $time . " seconds faster than single

Could the speed have more to do with whatever database server you are
using, than with PHP? I assume database since you are querying something.
Just curious.
And Jay: I'm using Lotus Notes R6, not much I can do about top quoting.

meatbread.
So basically, I run the test 20 times, include 1000 _different_ files
for both single and double quotes in each test, and come up with a mean
of about 3 one-thousands of a second in favor of double quotes. Not
totally scientific but produces a fairly accurate result.
You on the other hand, run a test including the _same_ file 10,000 times
(which brings into play error handling if you define a function in that
include file) and produce a result with a difference of about 7
one-hundredth of a second. A bit less scientific, but still produces a
fairly accurate result.
With all that said...
1) The time difference in either test if way too small to make a
difference.
2) It's a far cry from one of your earlier posts which read, "Well....i
have a 30k script, with double i get 8 or 9 seconds, with
sigle i get 0.05 or 0.08 seconds. The script basically made a lot of
querys, its part of a user manager module of a system im writing."
3) Meatbread indeed.

between the two would be negligible.
This has been talked about on this list so many times.
Another way to put it would be:
...because in most real-world scripts, the execution time for this kind
of operation (the string parsing) is negligible compared to the script's
total execution time. So even if you could reduce the time it took to
parse strings to nothing, you wouldn't speed up the total execution time
very much.
If you want to optimize the performance of your scripts, there are
probably a lot of other things that should be much higher on your
priority list than substituting double quotes with single quotes.

hi..
after a lot of fruitless searching via google, i've decided to ask here...
does anyone know of an app that will allow a site to provide functionality
similar to 'yahoo groups' to the users. i want to be able to allow users to
be able to create their own 'groups' and to be able to have the user allow
other users/members to join the group. i also want to be able to have the
user be able to admin the group, with the ability to manage members/handle
message posting/(up/download) pics/etc...
i asumed that there would be a number of these kinds of apps, i haven't
found any yet.
i have found plenty of bbs/forum types of apps that try to pass themselves
off as being in the 'yahoo group' area.
i've also seen the drupal based civic app...
thanks for any help/pointers/etc,....

When I went to a site that lists and compares CMS programs, I was
overwhelmed by at least 100 listings. Again, I would like to rely on
personal experience. What I am seeking is a CMS that will provide users
at my client (a Yacht Club) to update news items, and if possible,
update a calendar using a Web based editor. Not a full fledged portal CMS.
Also, it would be nice if it was written in PHP and use MySQL for the
server DB. Has anyone had experience with such a CMS?

Whatever you do, do not use PHP-Nuke or PostNuke. They are popular and
they seem good at the beginning, but you will regret using them after a
while. (Their internal design is not thought-through.)

Hey there-

that comes with, I get this error:
*Fatal error*: Call to undefined function: session_save_path() in

*I'm not sure why this is coming up since the session support is

install of SuSE 9.1 with apache2.0 and php4.3, is there something I
might have missed in the php.ini file I need to adjust?

Subject: strncmp function
Date: Wednesday 30 March 2005 01:14 pm
From: Russ <[EMAIL PROTECTED]>
To: PHP General <[email protected]>
I'm new to php and linux. I am trying to replace a password program I used
under windows with a mysql based login. I want to compare the first character
of the first and last name of the user for a capital letter. My login program
passes a user name and password. Below is a start to the program but I'm
alittle confused on how to set str1 to check all letters of the alphabet. Can
anyone point me to a document or give me an idea on how to do this? I can not
use .htaccess do to ISP (host) rules. Access is to a members only sectionof
the webpages for my Lions club.
<?php
$fname=John;
$lname=Smith;
if(strncmp(S,${lname},1) ===0) {
?>
<h1>strncmp() must have returned returned non-false</h1>
<?php
} else {
?>
<h3>Strncmp() must have returned false</h3>
<?php
}
?>

Why? What does that accomplish?

Where's the quotes?

non-false = true

Rewrite:
<?php
$fname = "John";
$lname = "Smith";
if(preg_match("/[A-Z]/", substr($fname ,0 ,1)))
{
echo "first letter is uppercase.";
}
else
{
echo "first letter is not uppercase";
}
?>
There might be a better way than a regex but that's the first thing that
came to my mind.
HTH,
Chris.

Thanks Chris, I'll try that. I'm not really a programmer, done a little and
trying to learn as I go. I had quotes at one point but took them out tring
to get it to work.

It appears the parse error is at the end of your opening link tag, so PHP
doesn't know what >.HtmlEntities($url) means. I'm at work so I can't test
it, but that appears the culprit to me.
$url = "<a href=\"$url\">" . HtmlEntities($url) . "</a>"; should suffice.
Please don't make a habit of changing the case of built-in PHP functions.
