I have created a function that will measure the width of a text string in pixels. It works ok.
If you have optimizations, please let me know.
Thanks,
Jacob
function txt_width ($txt) { $width = 0; $txt_len = strlen($txt); for ($n = 1; $n <= $txt_len; $n++) { switch (substr($txt, $n, 1)) { case 'l'; case '.'; case ' '; case '-'; case 't'; $width += 3; break; default : $width += 8; break; } } return $width; }
the width depends on the font used (monospace or not), the kerning used, the size of whitespaces, etc. you can't say "the width of X will be Y" without knowing the font, font size, kerning, etc.
I know, I had thought about that I could multiply the result according to what I know about the font.
It works ok so far for my purpose, which is to measure the width of menu elements in dhtmlcentral.com's coolmenus.
