Oops. We want to remember the position of the result set, so it's
$result that should be static, not $myrow. In addition, you'll have
to put a check at the top of the function to see if $result is still
valid, and to have it not re-run the query if it is. Otherwise you'll
get the first row back every time. Come to thing of it, it's probably
just easier to get all the songs back at once and then do a foreach.

Is this not *wrong*. It sounds to me like fake laziness. Nothing drives
me bonkers more than trying to track down a variable that is inherited
from who knows where.
Perhaps I'm missing something. I've recently worked on a lot of PHP
code written by others and it's a nightmare trying to track down where
a variable is defined and where it's value might be changed. Perhaps
there is some tool I can use to trace this. I dunno.
Am I correct in my aversion to globals or I am I missing their true
value and perhaps some tools I could use when working on apps that have
more than 50 php files floating all over the place and no
documentation.

If you initialize all your local variables, there is nothing wrong with
having register_globals on. Well-written apps run quite nicely and
securely with them on. The reason to turn them off is to protect yourself
from crappy code.

imageCreate will create an image, but its palette will be very limited, so
when you try to copy your photo onto it, it will maintain the palette of the
original picture. Obviously, this is not what you want, since the picture
comes out looking all grey and faded (probably 8-16 colors!).
What works for me is creating a blank image using imageCreate(), then saving
it as a temporary jpeg (using imageJpeg). This action will set the palette
of the image to a jpeg's palette (close to 16-bit or better colorspace). If
you imageCopyResized over this temp.jpg (which you need to create whenever
you run the script to ensure sizing is perfect), it will come out with the
full palette of colors.
Pseudo code:
<?
$dest_h = whatever your calculated destination height is;
$dest_w = whatever your calculated destination width is;
$src_h = height of original image;
$src_w = width of original image;
// create the blank limited-palette image
$base_image = imageCreate($dest_w, $dest_h);
// convert and save it to temp.jpg
imagejpeg($base_image, 'path/to/temp.jpg');
// get the image pointer to the temp jpeg
$image = imageCreateFromJpeg('path/to/temp.jpg');
// get the image pointer to the original image
$imageToResize = imageCreateFromJpeg('path/to/image_to_be_resized.jpg');
// resize the original image over temp.jpg
// since you have GD2, you could also use imageCopyResampled
imageCopyResized($image, $imageToResize, 0, 0, 0, 0, $dest_w, $dest_h,
$src_w, $src_h);
// values for output jpeg quality
$jpegQuality = 75;
// create the resized image
imageJpeg($image, 'path/to/thumbnail_name.jpg', $jpegQuality);
?>
Then all you have to do is a little cleanup with imageDestroy() and you
should have a nice looking thumbnail!
I usually add a line like this to the script to make sure everything went
smoothly:
<?
echo '<html><head><title>Thumbnail Generator</title>'
.'</head><body><img src="path/to/thumbnail_name.jpg">'
.'</body></html>';
?>
It lets me see the quality of the thumbnail the second the script completes.
Try it - you'll get perfect thumbnails every time. I used this technique
for all of the pictures at www.arkestraclandestina.com with GD1.6 - and all
of them actually had custom color profiles! Works like a charm.
I like this method because I can be sure that the script won't break on
sites with older PHP and GD versions - which is an important consideration
when you're deploying applications to other sites...
However! If you are sure it will only be run on a PHP4, GD2 system, you can
avoid all of the temp jpg madness altogether by just altering your code to
use imageCreateTrueColor() instead of imageCreate()!! ;P Easy as pie!

Subject: [PHP] GD lib. image quality!
Hello!
I wrote a little script for generation thumbnails of larger images....
<code>
$origImage = imageCreateFromJpeg($sourcePath."/".$currentImageName);
$thumbnail = imageCreate($thumbWidth,$thumbHeight);// create empty image
imageCopyResized($thumbnail,$origImage,0,0,0,0,$thumbWidth,$thumbHeight,imag
esX($origImage),imagesY($origImage));
imageJpeg($thumbnail, $targetPath."/".$thumbNamePrefix."_thumb.jpg"); //
Store it
imageDestroy($thumbnail); // cleanup
echo "<br>Image ".$targetPath."/".$thumbNamePrefix."_thumb.jpg"."
created successfully!";
</code>
then, I've noticed that the quality of the thumbnails created is very bad!
my "phpinfo()" page shows "2.0 or higher" as GD version
So, I'm wondering whether I'm doing something wrong in my code or whether
there exist a better library to use with PHP ... a library able to generate
good quality JPG files...
Thanks in advance.
Arcadius.

If you have GD2 I'd advise using imagecopyresampled, as I found using imagecopyresized often resulted in blue or grayish images, while imagecopyresampled resulted in normal looking images.

imagecopyresize() just skips pixels in order to reduce it in size. imagecopyresampled() will take the average of adjacent pixels and therefore produce a much better scaled down image.

I think you were on the right track with your first response. Selecting a count(*) gives you the number of rows returned without the overhead of actually returning all of the rows to PHP. Most people will rename the count as something more easy to reference (and/or more descriptive) in the result set:
select count(*) as num_movies from movies where actor='Val Kilmer';
What Jason was trying to explain is that the data you are looking for is actually in the query you performed. You specifically queried for the number of rows. Your result set consists of a single row with a single element, num_movies.
Happy hacking.

Hi guys,
Am writing a web based mailclient (obviously with PHP+IMAP), In the 'ReplyMail' script, inorder to add the "> " string at the beginning of everyline, I used the following code, <? $replymessage = $replymessage.str_replace("\n", "\n> ", htmlspecialchars(trim(imap_body($mbox, $msg)))); ?>
This is giving an output with one additional \n in the TEXTAREA, like below
<- strip -> >Hello Chandu,
>How are you. How is your coding going on.
>I'm on Mandrake 8.2.
>/Chandu <- End of strip ->
Any workarounds for this,
I hav seen the code of many PHP based IMAP client's but found out that all of those I checked are working in the same way as aboove. Squirrelmail is working as needed but I'm not able to locate where exactly the code I needed is, in those bulky files.
so as a last resort I've posted here.

Does this directory exist? Does the user that your web server is running as have permission to write files in this directory?
> Anyone know whats going on - PHP.net was of a absolutely no > use and I am very new at file uploads - any help appreciated!
You might find that setting up a simple test page with the file upload and little else will help you. For starters you might even just set up a test page that echos back the name of the file and the temp name of the file - then you can see if your form is sending the right information. From there try moving your uploaded file and if this fails then you've either got a syntax problem with your code or you've got a permissions problem on the server.
http://www.php.net/manual/en/features.file-upload.php includes examples of doing a file upload and the comments following it include many useful tips. In the end, though, you're best move is probably to start simple and make sure it works before adding in all the other stuff that you might want to do.

I am not really replying to your question, but just as a remark, in php, a variable needs to start with a letter or and underscire. (must be detailed in the doc) So I have absolutely no idea how PHP will interpret this line : <input type="hidden" name="5400" value="1000"> (and I would be curious to know how it actually does ! can you tell me ? )

Eric
attached mail follows:
using register_globals=on and trying to echo out the $5400 errors as expected, but php sees the correct entry in the $_GET superglobal array as it should. running a simple foreach($_GET as $key => $val) returns a key of 5400 and a value of 1000 on a page with the querystring of page.php?5400=1000, so you should be able to pull that info into another variable correctly.

Hello Rasmus,
Ok I understand the array_intersect and have gotten that to work. I just don't understand the second part using the foreach and unset().
this is what I have it gives me three separate list

$arraylistA=explode(" ",$listA); $arraylistB=explode(" ",$listB);
$result = array_intersect ($arraylistA, $arraylistB);
foreach($arraylistA as $valueA){ echo "ValueA: $valueA<br>\n"; } echo "<br>"; foreach($arraylistB as $valueB){ echo "ValueB: $valueB<br>\n"; } echo "<br>"; foreach($result as $valueC){ echo "ValueC: $valueC<br>\n"; }

Hi !
there is no way to apply a config file to apache without restarting the webserver.... the only way I know (which really does not mean that it is the only one !), is to use the command "apachctl" or "httpd". But those command need to be launched as root, I think (try to login as root, then to a "su nobody", and try to launch apache like this. If it works, then a simple exec("apachctl restart") should be enough, check the syntax of exec() there : http://www.php.net/exec ).
If you need to be root to start apache, then you'll need to either build a script that changes user to root, and lauches "apachectl restart" once logged ( try the "sudo" command in your shell, it is available in any linux distribution, or try freshmeat.net ), or use the setuid bit so that any user can start httpd with root provilege (which would work but wouldn't be recommende. "man chmod" to know more about this).

Yes, you can make Apache reload a config file without restarting. You must send it a SIGHUP:
kill -HUP `cat /var/run/httpd.pid`
If you execute this as nobody, I believe it will work, but I haven't tested it.
Also, I believe Apache will restart when given a "kill -1". If the above suggestions works, so will this.
Happy hacking.

Perhaps, if you check the manual you'll see if a certain function is already "defunct".
Checking mysql_connect() here,
http://www.php.net/manual/en/function.mysql-connect.php
shows that it's even "better" than before.
So, most probably, when the person who set up the server didn't include mysql support in php. It'd be better to ask the person to enable it.
BTW, you can do phpinfo() and see if mysql support is enabled or not. (Of course, you also need to check IF MySQL is even installed...)
