I've been told that there is a "webthumb" command line tool to do just
what you ask as a JPEG.
At least I *think* it was called "webthumb"...
Maybe from the GD folks???
It's out there somewhere, and I was going to look into it, but...
You'd feed it a URL and it gives you an image. You need X installed,
so it can run X in the background and render it.

That's the kind of marginal hack I was hoping to avoid ;^) However,
it did lead me to http://khtml2png.sourceforge.net/ which seems far
more like it. Now I just have to persuade it to compile.
Thanks.

It is indeed called webthumb: http://www.boutell.com/webthumb/
After installing firefox on my server, tweaking webthumb to use
firefox instead of Mozilla, a bit of messing with xauth settings, and
I've got it working! It seems like a more polished alternative to
html2jpg. It uses Xvfb for a local display so you don't need a real
one, and it doesn't interfere with remote X sessions, though firefox
complains if you try to run it on both X displays at once. Now I just
need to go find a borderless chrome package for ff...
khtml2jpg is definitely a more advanced solution as it contains its
own browser and is thus not limited by screen size - you could grab a
page 10,000 pixels tall if you wanted to - and it can monitor browser
state e.g. so it can know when all images are loaded instead of just
waiting for a bit. Flipside - it's not working for me...
Thanks very much for the tip, very glad to have finally found a
solution.

I have a directory with the files:
/config/A
/config/B
and
/config/C is a symlink to /config/A.
Via php I unlink /config/C:
$FILE = '/config/C';
while(file_exists($FILE)){
unlink($FILE);
clearstatcache();
}
When run, the first time through the loop $FILE is removed from disk
as it should.
The loop then continues forever with file_exists() returning true, but
unlink() returns false with the error message "Warning:
unlink(/config1/C) [function.unlink]: No such file or directory in
/www/script.php on line 10"
If I do this:
$FILE = '/config/C';
unlink($FILE);
cleanstatcache();
symlink('/config/B', '/config/C');
I get the error message:
Warning: symlink() [function.symlink]: File exists in /www/script.php
on line 11
However the link had been deleted.
The symlink /config/C is read via file_get_contents() before the
unlink and relink is performed.
I have also done the following:
$FILE = '/config/C';
unlink($FILE);
`ln -s /config/B /config/C`
Which works as expected, the old link is replaced with the new link,
however any attempt to open and read from the new link returns the
contents of the old file.
How would I be able to get the expected behavior from PHP. I expect
that the problem has something to do with the symlinks being used.
Any assistance is appreciated.

This might be an issue with the OS or Filessystem. The code
works just fine for me, i dont even need the clearstatcache().

Thank you for checking on this.
I am using debain stable with a 2.6.14.3 kernel. The filesystem in
question is ext2 on a 48 MB ramdisk.
I also did the following on another machine using ext2 on a harddisk
with command line php.
<?php
/*
-rw-r--r-- 1 user user 0 Dec 21 12:41 A
-rw-r--r-- 1 user user 0 Dec 21 12:41 B
lrwxr-xr-x 1 user user 1 Dec 21 12:43 C -> A
-rw-r--r-- 1 user user 91 Dec 21 12:41 test.php
*/
$FILE = 'C';
while(file_exists($FILE)){
echo "$FILE exists\n";
echo `ls -l C`;
if(!unlink($FILE)){
echo "Unable to delete $FILE\n";
echo `ls -l C`;
}else{
echo "Deleted $FILE\n";
}
echo "====\n";
}
/*
Output:
>php5 ./test.php
C exists
lrwxr-xr-x 1 user user 1 Dec 21 12:59 C -> A
Deleted C
====
C exists
ls: C: No such file or directory
Warning: unlink(C): No such file or directory in
/home/user/x/test.php on line 14
Unable to delete C
ls: C: No such file or directory
====
C exists
ls: C: No such file or directory
Warning: unlink(C): No such file or directory in
/home/user/x/test.php on line 14
Unable to delete C
ls: C: No such file or directory
====
*/
?>
This shows that apache is not responsible for the problem.
Note also that if I delete A and C within the loop the code works as
expected and the loop only executes once. So file_exists() is seeing
"A" when I tell it to delete "C" and unlink is seeing "C" as it
should.
Any ideas where to start to look for the cause of the problem?

Hi,
Have a load of dates in the format DD/MM/YY. Thet are stored as a VARCHAR on
a mysql DB.
I need a way to sort them into order(most recent first)
Using the QUERY $query = "SELECT doc_date FROM papers ORDER BY doc_date
DESC";
this just arranges them by day. e.g
30/12/2005
30/11/2005
22/12/2005
19/12/2005
17/12/2005
12/12/2005
10/12/2005
06/12/2007
06/09/2002
05/12/2005
05/09/2005
Now I have tried to use strtotime() but I find this needs a timezone (GMT)
to work and I don't know if the server supports it. Also I find strototime()
and mktime() very confusing and a things go wrong of you work in GMT because
we also have Brittish Summer Time where the clocks get put back/forward at
certain time of the year.
Is there a simple function like sort() that could do it??

Hi!
Its a real shame your dates aren't stored in a DATE type field instead of
VARCHAR, because you can just sort them in your query with "order by DATE".
If its possible, you would really benefit by converting them and storing
them in the proper DATE type field.
That being said, I suppose you could "explode()" them into an array then
figure out how to sort them from there.

You COULD sort them if the date was stored backwards, ie. Year/Month/Day

Couldn't you use cast() to cast the values first? Something like (untested):
SELECT CAST(doc_date AS DATE) FROM papers ORDER BY doc_date DESC

Currently, I'm running PHP 5.0.4 (only because it's the only one I can
get to work on my FC4 x64 install!), but for some reason, using pixel
sizes under 8, or using bold fonts, makes the text look horrible.
My old host (1&1 in case anyone else has them..) had this working well,
but I have no idea what their settings were.
I've heard that editing the gd.h file to change the resolution from 96
to 72 helps, but I'm assuming I'd have to recompile something for that
to take effect, and I can't find a PHP-GD Source RPM for my arch.
What must I do to get everything smooth again?
Fedora Core 4, x64
PHP 5.0.4
PHP-GD module (separate RPM install)
Freetype 2.1
gd-2.0.33
Thank you.

We use EnterTrack (http://www.entertrack.org) in my company. We've been
using it for about 2 years and are pretty happy with it. I've also done
some customization to our EnterTrack installation in order to integrate
it with our company intranet. It's focus is on tracking/archiving
issues, so it doesn't have any functionality for asset management. But
it does have a pretty flexible group/permissions system that allows you
to set up multiple groups and provides various levels of access to
users.
At one time, I evaluated phpMyInventory for asset management. There is
the free version (http://phpmyinventory.sourceforge.net/index.php) and
there is also a commercial version. We ended up going with Network
Inventory Analyzer from Alloy
(http://www.alloy-software.com/nin/pro.html). It's a commercial
package, but it was inexpensive (~$1000 for 150 nodes) and met our
needs.
Hope that helps!

What I'm trying to do is to parse URLs of different sorts, ftp, http,

The hard part is when a user has already entered a complete link..
In short:
http://www.server.tld/page.html
should be converted to:
<a

That part works fine, but if the user enters:
<a href='http://www.server.tld/page.html'>click here</a>
it all becomes a mess... Can somebody please make a suggestion on this?
