Re: Interactive mode not very useful

I'm running PHP 5.2.6 on WindowsXP. When I try interactive mode with

Not really. But then if you have a syntax error, your code can't be executed anyway, so why stay in the interpreter? It would be nice if it let you correct the error, but it doesn't. That's why I seldom use the interpreter in interactive mode, and even then only for programs of a few lines.

In Windows, once you've reentered the interpreter, you can use the up/down arrow keys to scroll through the keyboard buffer. When you're in the interpreter you'll have the lines previously entered in the buffer. A bit awkward, but it does help a little.

Otherwise, I just use an editor to create a file and leave the editor window open while I test the script.
