Finding A Word's Length In Pixels

Here's a toughie for me.

Using the GD library, I want to print a word or string as an image,
but with some constant amount of padding around it. The text is not
known beforehand. In other words, something like

________
| |
| flan |
|________|

I'm very new to GD, but offhand the only solution that comes to mind
is to create a very long general-purpose image, print the text at (x1,
0), measure the word there, destroy the image, then create a second
image with dimensions calculated from before. That seems rather
sloppy. Is there a better alternative?

If you use freetype2 fonts, have a look at:
imageftbbox()
imagefontheight()
imagefontwidth()

That should do the trick.

text.
Margin on the image, using CSS?

I promise you, I have a reason that makes plaintext insufficient. It
seems rather hasty to question and fix my project when I haven't said
a word about it.

requirements should be when that project hasn't been described. A
need was posted, so the proper response is to address that need
rather than question it. There are plenty of reasons why someone
may want to render text as graphics:

* Graphical display of data requires text on the graph axes and
legend, and that makes most sense as part of the graphic.

* CAPTCHA requires the use of text in graphics.

* Using some text as graphics is a good way to shield content from
spiders and crawlers.

* Clickable buttons containing text descriptions.

* Etc.
