Get string 'pixel width'

[RadGH]

I'm trying to make my script show text, but if its long it will attempt to shorten it.

Example:

"This is a really long title"

be shortened to "This is a..."

Right now I'm just shortening it to the first 10 characters, but it can still leave the text field I'm using if you use all large characters, or be too small. Example:

QQQQQQQQQQ
iiiiiiiiii

Those are both 10 characters. Is there a way to detect the width of a character with the PHP GD, such as write a text string to an image and output the width of the image? I looked through the GD manual and this is all I can find. I have no idea what its for, but I don't think its what I need.

[man]imagefontwidth/man would do what you need it to. It will give you the width of the font you're using. Then you can just take the width of your image, divide it by the width of the font to give you how many characters across it will fit.

Take a look at [man]imagettfbbox/man, [man]imagepsbbox/man, and [man]imagettfbbox/man.
