Hello list
I use the following code to shrink some photos.
$directory='/var/www/html/offroads/tmp/';
$dir=opendir($directory);
while($file=readdir($dir)) {
$dirfile=$directory.$file;
if(is_file($dirfile)) {
copy($dirfile,$directory.sm/sm_.$file);
$imgReal = ImageCreateFromJPEG($dirfile);
$x = ImagesX($imgReal);
$y = ImagesY($imgReal);
$newX=$x*0.1783;
$newY=$y*0.1783;
$img = ImageCreate($newX,$newY);
ImageCopyResized($img, $imgReal, 0, 0, 0, 0,
$newX,
$newY, $x, $y);
//$newimg=imagecolorstotal($img);
ImageJPEG($img,$directory.sm/sm_.$file);
clearstatcache();
}
}
closedir($dir);
My problem is that the color results are very bad. How can I take picture
with good colors?
Thank you

Try using imagecopyresampled() instead of imagecopyresized(). It uses a more
precise algorithm which means: more time to complete. But since it seems
you're creating a cache of resized images that won't mather once the resize
its done.

[PHP-DB] multi-table insert
Hello everybody! I am very much a newbie in PHP, but enjoying the learning process. Here and there I get tangled in the logic of certain problems. Anyway, I have a database about interns and this database has multi-tables told data of interns, for example personal information, education qualifications, computer skills, languages etc. The relationship of the tables is based on the intern's username. What I am trying to do is have a form, which an intern can fill in so that details are inserted into the database. Since I am populating a number of tables in one go, what's the best way to implement this? The main table is the personal information one, which has the username as primary key, and the rest of the tables username is the foreign key. Obviously I need the to pick the username from the main table and insert it into the other tables. How best can I do this? Sorry this is a bit like an essay, but please assist. I know it looks obvious to the experienced guys, but am having a bit of a problem. Thanks Eustace

I would try something like this:
if(isset($_REQUEST['send_mail']))
{
mail($_REQUEST['address_mail'],$_REQUEST['subject']
$_REQUEST['message']);
unset($_REQUEST);
}
That should wipe all the variables in $_REQUEST before the user clicks
reload. It will not work on a global variable if you use it inside a
function. There are other ways to do the same thing, but I think that
should do it.

As a follow up, if you want to use that in a public environment, you really
need to run the $_REQUEST array through something like strip_tags() at the
very least, and probably write your script in such a way that nobody can
inject headers into the form for spamming. The archives of the PHP mailing
list include ways to do it.

[PHP-DB] capture a webpage to later process it
I want to read the results of an URL address, to later process it and
insert part of them as internal code.
If I use include or require, they inserts ALL the resulting code, but I
want to do something like:
blah, blah, blah
?php
$result_webpage = somephpfunc('http://other.sit/externalpage.html');
if
(eregi(result:([:alnum:]+).*([:alnum:]+\.jpg),$result_webpage,$array_match))
{ echo h2External status:.$array_match[1].brimage: img
src=\..$array_match[2].\/h2; }
?
blah, blah, blah

If you have fopen wrappers enabled (see
http://us2.php.net/manual/en/ref.filesystem.php#ini.allow-url-fopen)
then you can simply use file_get_contents() to read the web page into a
string. You can then manipulate it with regexes like so:
$Url = 'http://www.php.net';
$ThePageContents = file_get_contents($Url);
$TheNewPageContents = preg_replace('/PHP/', 'Ruby :)', $ThePageContents);
echo $TheNewPageContents;
