I've just made this when i was messing about with GD functions in PHP, it is a progress bar type thing (not sure of the exact name). It takes 2 inputs, the total and used then creates a status bar type thing, could be useful for showing the amount of disk used.
Heres the main code:
ProgressBar.class.php
It creates it in PNG format, which can be changed but i've been experimenting and PNG seemed to eb the smallest filesize, below are example usages of it:
Basic - will take the default values set in the script
Or a more advanced version, where you can set additional variables (not everything needs to be set)
The only variables that need setting are total and highlight, any feedback appreciated
Thanks,
Lee
