I personally don't think this is a very healthy contest. It discourages
comments, and use of whitespace to make code readable.
I'd perfer a contest that rewarded code readability, and maintainability as
well as minimal keystrokes. After all you only enter the aforementioned
keystrokes once. Perhaps one like codegolf, with an enforced coding style (
eg KR Style, or GNU Style)

I completely agree. This kind of contests do not provide any measure of the
good qualities of a programmer working as part of a team. The objectives
ussualy end up being something of the sort: "let's see who can fit the most
in a for declaration".
Anyway... as you say, it would be nice to have a contest that rewards
readability and maintainability... but, how can we messure that qualities in
this type of games? Should your code be praised by others and voted on? Is
that reliable? I think enforcing a coding style is too restrictive... Also,
how do we measure the declarativity of var and function names?

The value of these games is that they give you interesting problems to
solve without forcing you to maintain the code. That's the entire point.
It's exactly the sort of thing that's fun to write when you have to make
a living from your code the rest of the time. If you want to write
quality software in your free time then you start/join an FOSS project
and put the code to good use.
Nobody is claiming that this is a good way to write code or a good way
to learn PHP, it's just for fun.

For some real trouble, try the International Obsfucated C Code Contest:
http://www.ioccc.org/
These contests like Code Golf are just for fun, I can't say that they
encourage bad practice as long as you understand what the contest is
about.
That aside, I think that it would be very beneficial to the community as a
whole if a contest was started that encouraged readability and good
practices.
The scoring and judging could be done by a panel, but I think that it
would be more fun if the community itself was able to vote on various
attributes; readability, efficiency, general approach, originality, etc.
Allow people to comment on each entry. I don't know about the winner
getting anything besides bragging rights, but it if gets large enough
maybe there can be a few corporate sponsors giving away licenses or
something. Who knows?
I think it would be a lot of fun if well executed.

You're right, it's just for fun.... but... they could still be fun and be
useful. These kind of games could easily be used for education and training.
We all know that the quest/mob grinding factor can be very addictive, why
don't use all that energy for the good? You could still learn how to do a
good job while having fun...

We're probably talking about that silly contest started the other day
to calculate pi to 1000 digits...
:-)
My best guess is that the C code is relying on type-casting to hack
something somewhere.

If you think of the Open Market of software "out there" as "the game"
and people's decisions to use or not use it, then you've got a pretty
good contest.
And PHP is winning. :-)

"ical_parser" sounds like it is a function which sucks in information from
other computers. if one of those computers is down, then your program will
probably timeout while waiting for the information.

Hi All
This is all very weird and it may be that it isn't a php problem
after all.
Here is line 494 in ical_parser.php
ereg ("([^:]+):(.*)", $line
Additional information is
a) the mac that publishes the ical is always up, no probs there
although I should check if a system update has been done recently.
b) The webserver that hosts the calendar is definitely up because all
the other web pages work.
c) The athentication definitely works since if I put in the wrong
username and password it comes back with an error.
d) the whole thing worked perfectly until a few days ago. I've
managed to get it up again by restarting httpd but then it fails
again shortly after.
e) I've made no changes to the webserver.
f) Is it possible that its trying to access too much data from the
calendar i.e it is possible to go back 18 months and look at the
schedule.
I'm just about to archive the existing scanner.ics file and republish
another one to see it that works.
thanks

I like kdesvn. It actually uses the svn API so it isn't just a wrapper for
the command line.
http://www.alwins-world.de/programs/kdesvn/
If you use SVN+SSH, and you run kdesvn from the command line, then it will ask
you for your password on the command line. Just a little hint.

Geeeeeee, way to fight back against the shrinking distance of the global
community brought to you by the Internet. I'm just curious why so many
posters for jobs feel the need to force a local boundary. Is the quality
of work somehow better because you can knock on their door?

I need to read urlencoded data from POST request. So far I have tried

Sorry folks, this is a long one...I've re-read a bunch of the
documentation, and I can't find a solution.
In debugging an out of memory condition, I found that PHP doesn't seem
to garbage collect unreferenced objects. It seems to work fine for
anything other than objects. (Arrays, strings, integers, etc.)
Here's a simple example: define a class, create 3 instances, destroy
them in reverse order. I would expect that after each unset and/or NULL,
the memory usage would go down, they don't. See the output below.
<?php
class Tester {
protected $test1;
protected $test2;
protected $test3;
protected $test4;
public function __construct() {
$test1 = rand();
$test2 = rand();
$test3 = rand();
$test4 = rand();
}
}
echo memory_get_usage() . "\n";
$t1 = new Tester();
echo memory_get_usage() . "\n";
$t2 = new Tester();
echo memory_get_usage() . "\n";
$t3 = new Tester();
echo memory_get_usage() . "\n";
unset($t3);
$t3 = NULL;
echo memory_get_usage() . "\n";
$t2 = NULL;
echo memory_get_usage() . "\n";
unset($t1);
echo memory_get_usage() . "\n";
This outputs:
43344
43928
44232
44568
44640
44640
44640
Note: the memory usage remains constant after the objects are allocated,
even when they're unset/NULL'ed.
Some of the user contributed notes on the PHP documentation suggest that
the memory is actually freed and available for use by other
variables/objects even though memory_get_usage() says otherwise. Another
little test seems to disprove that too... The idea here is to allocate
close to 8 MB, then free it to show that it can allocate that data
within the memory limit. Then allocate enough class instances and free
them again such that the memory usage increases enough that the same
data allocated and freed initially doesn't fit anymore. If PHP did
indeed free the objects, the data would fit the second time too...
<?php
ini_set('memory_limit','8m');
class Tester {
protected $test;
public function __construct() {
$this->test = rand();
}
}
echo "Initial Memory Usage: " . memory_get_usage() . "\n";
$mb = 6 * 1024 * 1024;
echo "Allocating 7 MB of data...";
$dat = "";
for ($x=0;$x<$mb;$x++) {
$dat .= "x";
}
echo "Memory Usage: " . memory_get_usage() . "\n";
unset($dat,$x,$mb);
echo "Unset Usage: " . memory_get_usage() . "\n";
$num = 32767;
$objects = array();
echo "Initial Memory Usage (2): " . memory_get_usage() . "\n";
echo "Allocating $num objects...";
for ($x=0;$x<$num;$x++) {
$objects[$x] = new Tester();
}
echo "Done. Memory Usage: " . memory_get_usage() . "\n";
echo "Freeing $num objects...";
for ($x=0;$x<$num;$x++) {
unset($objects[$x]); $objects[$x] = NULL;
}
echo "Done. Memory Usage: " . memory_get_usage() . "\n";
$mb = 6 * 1024 * 1024;
echo "Allocating 7 MB of data...";
$dat = "";
for ($x=0;$x<$mb;$x++) {
$dat .= "x";
}
This gives:
Initial Memory Usage: 44248
Allocating 7 MB of data...Memory Usage: 6335888
Unset Usage: 44448
Initial Memory Usage (2): 44504
Allocating 32767 objects...Done. Memory Usage: 7752920
Freeing 32767 objects...Done. Memory Usage: 2807080
Allocating 7 MB of data...
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to
allocate 1 bytes) in /home/janderson/svn/memtest.php on line 44
Am I missing something? (Is there a force_garbage_collection() function
somewhere that I'm missing?) Any suggestions/workarounds/anything would
be most appreciated.

Hi,
I am relatively new to php and am trying to set up a file upload
process for my website. I have read through the php security
documentation and a number of the security-related questions on these
lists and am attempting to implement as many of the measures as
possible.
One of the suggestions I have read is to have the uploaded files saved
somewhere outside of your root directory. Unfortunately I cannot do
that as my root directory is simply www.myDomain.com and not
".public_html/" and I am on a shared server where my root cannot be
changed (I have already asked). So, I am trying to keep the
permissions on my "saved_files" folder as tight as possible except
when the actual upload occurs. I this as follows:
1) The actual file upload comes through Flash8, and when the user
uploads a file it is sent to
www.domain.com/flash8directory/upload.php, which is in the same
directory as the Flash8 upload application.
2) upload.php first chmod 0740 the "saved_files" folder (which is
located at www.domain.com/flash8directory/saved_files/). Then it does
security checks to make sure an appropriate image has been uploaded,
and if everything looks good it moves the uploaded file to
"saved_files".
3) The Flash8 upload application is notified of the completion of the
upload and downloads the new image it its viewer.
4) Once the download is complete and Flash8 no longer needs to work
with the file, the Flash8 application notifies a separate php script
by sending the variable "complete=1" to lockdown.php (located at
www.domain.com/flash8directory/lockdown.php), which runs the following
simple script:
<?php
$success = 0;
$complete = $_POST['complete'];
if ($complete==1) {
if(chmod("./saved_files", 0100)) {
success = yes;
echo "success=yes";
}
}
?>
This script works and "saved_files" is set to chmod 0100, but here is
the problem. If I then navigate directly to the url of the uploaded
file by entering its path in my
browser(www.domain.com/flash8directory/saved_files/uploadedFile.jpg),
the uploaded file appears in my browser! However, if I then refresh
the browser I get the desired error message saying I do not have
permission to access that file. Also, other browser windows never
have access to view the uploaded file, only the browser from which the
file was uploaded.
Any thoughts on why I can view the uploaded file even though it has
been set to chmod 0100? I'd really rather not have those files
accessible to anyone, as an extra security layer.
Thank you for your help!
Andy

I don't quite understand why you cannot save to another catalog.
is www.myDomain.com yer actual directory name of merely the domain?
If either, login to yer domain and simply go either one step up, is that
possible?
You can also make use of a .htaccess file inside a sub directory to keep
others from it till you have checked the file, then move it out in the open
or delete after specifications.
Do you have access to /tmp ? That one is possible to use, in fact any system
wide directory writable by any/you is usable.

For the sanitization...
.*? could be something more like: [#a-z0-9A-Z]+
The # assumes you want to allow #ff0000 style colors.
Since this whitelists the specific characters you allow, it's probably
better than the strip_tags thing.

If you are comfy installing from source, visit each site and download
the version marked "latest stable release"
MAYBE for Apache stick with 1.x as there's not much point to 2.x with
PHP as you're stuck with pre-fork mode which means you might as well
just use 1.x as I understand it, or probably mis-understand it...
If you are not comfy with source, then whatever the distro is touting
as "stable" is probably the most stable for their distro...

Port the FreePascal to C first? :-)
I dunno... I mean, maybe there's some fancy FreePascal->C bridge
thingie to make it all work...
Can you include a bunch of C header files and make them work?
Cuz there's a TON of stuff in PHP C header files of macros and whatnot
that make it easy to write an extension.
Working without those or rolling those all over again in FreePascal
would be a nightmare, I suspect...
I just gave a talk at the Chicago PHP User Group "Extension Writing
for Dummies" based on my experience with: http://l-i-e.com/perror
I really think you'll have an eaiser time porting the FreePascal to C
than trying to marry C and FreePascal, but I'm no expert.

Here's where you MIGHT get bit in the butt:
1. Anything in a PRE tag is gonna suck big-time
2. Any kind of DATA from your db with multiple spaces will lose data
Now, you might maybe be able to fix these by religiously always doing
$output = str_replace(' ', ' ', $output);
on the DATA from the DB, or any kind of PRE tags stuff you use.
Or maybe in YOUR application, neither of these matters.
Test it with JUST the output buffer and without the whitespace crunch
-- You may find that the ob is the big win, especially if you have a
zillion echo statements going on.
