Right now I have been using nothing but notepad. The problem is that I cant find my errors that cause grey screens, and I cant color code anything. Any free programs I can download.. Im 15 years old... so please dont tell me to go buy something.
i use pspad editor, its a free program.
it has syntax color, and help to edit { } brackets.
and for html editor, dreamweaver is a very helpful program.
There are lots of free IDEs for PHP coding. One that I just came across that is fairly easy to setup (with a lot of functionality too) is Netbeans PHP IDE. If you just want a light generic IDE with syntax highlighting Notepad++ has it for PHP (as well as numerous other languages.) Here's a list of other PHP IDEs (via google search and not all free.)
Finally, your apache Web server, via PHP module, should be showing you errors in your browser. Make sure you are displaying errors (to avoid those "grey screens".)
Good luck!
There is also an extensive thread on the subject in the Echo Lounge, and no doubt many others that can be found by searching for words like "editor".
I'm closing this thread. If anyone has anything new to add, add it to the thread linked to above.
