I have created a php script. The script uses two php classes(GPL Licensed). Can I sell the script?? I've saw several commercial cms uses gpl script. I just want to confirm...
My understanding is, Yes you can. Attribution within the php file in a remarks style is all I ever see done to acknowledge the use.
thanks, I have a simple confusion. I will keep the GPL script untouched(with their respective owner copyright information). But attribution? can I just comment a small section like /* Created with the help of XXXX script by AAAAA (GPL) */ I can ready to do this. But it will be very bad to put such attribution on the visible webpage,where I am using that script. Does it will be any problem for me.
No. You don't need it on the web page for GPL. Creative Commons may require that in some cases. If you are using the classes as you found them, leaving the headers intact is all you need to do. I thought you were extracting stuff and adding it to your script. If that were the case adding a non displaying comment within your script such as // classes created by name used under GPL license. What you have above is fine and all you need to do. 100% legal. I do admire your desire to do it correctly.
Thanks, you have cleared my confusion.Though I haven't extract any thing from the classes, I just create a object of those classes and use it.
you can definitely sell or modify and sell it. The only thing you should not do is claim that the scripts is yours. for example I can down load linux distribution(Ubuntu maybe) and burn it and sell it. Nothing illegal.
