If I have a document containing, say:
<html>
<body>
<table>
<tbody>
<tr>
<td><font ...>foo1</font></td>
<td><font ...>bar1</font></td>
</tr>
<tr>
<td>
<font ...>foo2</font>
</td>
<td>
<font ...>bar2</font>
</td>
</tr>
...
How do I get at "bar2"? I tried everything, based on an xpath from
Firebug (Firefox plugin), but kept getting NULL.

try //table//font - that should give you all the font elements in
table elements. Given your layout, you're then looking for
$list->item(3)

Erm, why don't you use something like imagerectangle() ? It's far easier
and less resource intensive than having loads of single-pixel images for
each colour you want to use.

Thankyou Ashley,
as I only need 5 colors for each image, my idea was to create a single pixel
image for each color and save it on the hd (so that i don't have to create
it every time).
I've finally used this code:
imagecopymerge($base, $img1, 0, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img2, 100, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img3, 200, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img4, 300, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img5, 400, 0, 1, 1, 100, 500, 75);
($imgX are 1*1 images. I have a function that checks if they exists)
You can see the output here: http://aagmns47.facebook.joyent.us/sdna/.
I think that copying a 1*1 image (and as said i'll cache all 1*1 colors on
the hd) on a background is less resource-expensive than creating a coloured
rectangle every time, isn't it?

No, you use imagerectangle() directly on the final image, no need to use
imagecopymerge() at all!
$colour1 = imagecolorallocate($base, 255, 105, 180);
$colour2 = imagecolorallocate($base, 255, 255, 255);
$colour3 = imagecolorallocate($base, 132, 135, 28);
$colour4 = imagecolorallocate($base, 88, 105, 180);
$colour5 = imagecolorallocate($base, 0, 0, 0);
imagerectangle($base, 0, 0, 100, 500, $colour1);
imagerectangle($base, 100, 0, 200, 500, $colour2);
imagerectangle($base, 200, 0, 300, 500, $colour3);
imagerectangle($base, 300, 0, 400, 500, $colour4);
imagerectangle($base, 400, 0, 500, 500, $colour5);
It looks like more code, but you'll really appreciate it if you get a
lot of visitors who are triggering these images to be created
dynamically. Copying a single-pixel image and resizing it into a much
larger area is always going to be more costly than using the native
imagerectangle() function.
Also, the above way allows you to create the colours dynamically for the
image from within your script, and not have to create a new 1x1 pixel
image each time!

Ash

Sorry, use imagefilledrectangle() instead of imagerectangle() in the
example I just gave you!

Does anyone have any resources that demonstrates using jquery to have
an image or object slide in from the left and then fade in.
I would appreciate it.
Thanks!

And I assume you're going to be outputting everything with PHP? :p
http://jquery.malsup.com/cycle/ is a good plugin for transitions between
objects in JQuery. It's mostly used for image galleries, but can be
adapted to pretty much anything.
Ps. any chance you could trim your signature down a tiny bit. At the
moment, it's 3 times longer than your actual message!

Is there any php encoder like IonCube ?
Looking for an opensource solution.
My main target is to deliver encoded php codes so that it can not be
re-engineered.
