I was wondering about that. Since I am not actually hosting my ISP would
have to have it loaded (or compiled into their PHP implementation), right?
I'll have to do some legwork with my ISP and ImageMagic

efficient on disk space, creates thumbnails and populates the database
with as much "default" data as can be deduced.
After all of this was written, I decided to see if I could pull EXIF
data to supply some of the technical data for the DB. To my surprise,
the only EXIF data in the JPEG files was data in the File, Computed and
Comments sections.
Why don't the gd utilities retain the original EXIF data? Is there any
way to do so? I use the following gd utilities to resize and create the
new JPEG image files:
imagecreatefromjpeg
imagesx
imagesy
imagercreatetruecolor
imagecopyresized
imagejpeg
This is a known shortcoming of the GD library. You won't have that issue with
ImageMagick: http://php.net/book.imagick

You may be able to use http://php.net/dl to load the extension (you'll need to
build it to be compatible with your host and then upload it) but it's highly
unlikely they'll have the dl function enabled. Your best bet is to ask them to
add it to their environment.

Hi Andre,
I did a intranet with TextWiki (
http://pear.php.net/package/Text_Wiki/redirected )
TextWiki is a reliable Class to create Wiki using Php.
Regards.
Gerardo.

Markdown is a pretty good option for a wiki:
http://michelf.com/projects/php-markdown/
Textile is another option (and supports tables which markdown does not):

MarkItUp is a favourite plugin editor of mine - will allow you to work
with a lot of different syntaxes and users don't need to know them.

If you're considering sanitizing html instead of using a markup
language to convert into html, I'd read
http://blog.astrumfutura.com/2010/08/html-sanitisation-the-devils-in-the-details-and-the-vulnerabilities/
before settling on any tool to do the job. Far as I can tell, HtmLawed
isn't actually capable of sanitizing properly, according to the author
- unless it's since been updated to fix the problems mentioned in the
blog.

Readers,
A postgresql database (local disk installation) is successfully
accessed as a normal user:
psql -U username databasename
However, creating a php file to access the database has not been successful.
<html>
<body>
<?php
$db = pg_connect('dbname=databasename user=username');
$query = 'SELECT * FROM databasename';
$value=pg_fetch_result($query,1,0);
echo 'export of database is ',$value,'';
?>
<p>
why does this fail?
</p>
</body>
</html>
The following php code produces the user agent:
<?php
echo '$_SERVER['HTTP_USER_AGENT']';
?>

For needing a constants=array, I have to use
'public static $a = array(...)'
instead.
Why the language could not relax the restriction of constants?

As I understand it constants must be declarations not evaluations because
they're initialised during parsing not execution. Arrays are evaluations even
if they only contain literal values. It could be done, but it would require a
fundamental change to the engine and the benefit-cost calculation just doesn't
add up.

Hello,
I am trying to use php to put a copyright notice in a page footer. I'm
using the date function with the "Y" value for the year. Here's the
code:
<?php
echo date ('Y');
?>
This works great for a site done in 2011 but next year I'm going to
want to have 2011 and 2012 in the copyright notice, adding an
additional year the site's up. I'd appreciate some suggestions i'm
very likely overthinking this.
Thanks.
Dave.

I would use something simple like:
if(date('Y') == '2011') {
echo '2011';
} else {
echo '2011-', date('Y');
}

Something simple like this would work
$date=date('Y');
$startdate='2011';
if($date == $startdate) {
echo $startdate
} else {
Echo $startdate;
Echo '-';
echo $date;
}

... or in one line:
echo (date('Y') != '2011' ? '2011-' : '') . date('Y');
However, you might want to change that to:
echo '2011-' . date('Y');
at the first review after the start of 2012!

By that logic, so is a function call.
