well normaly you should be able to, make sure it has some wrapping tags like a span tag and use .width() function in jquery to get the width in pixels

Edit: it's not php but it's the only possible way i know of doing this

... it depends:)

so i wont get downvoted more than i already had..without getting a comment: it depends on:

• the used font

• the OS where this font is used (the font renderer on linux is produces slightly different results that the one on windows, and probaly the same rule applies on OSX)

• wherever you are using antialising and what kind of antialising is used

• wherever the font is bold or not

• the output medium (printed fonts are not identical to displayed font because of printer characteristics)

• the letter spacing

As a solution you may use GD to render the text into a surface, and try to crop it..
