Coding for Configuration Variances (magic_quotes)

[Anon]

Hi all.

I'm working on converting a discussion group app that I wrote into PHP and MySQL. I'd like to make it run on any platform with little configuration.

Seeing as how PHP is so configurable, I'm wondering what protections I need to code to prevent errors.

For example, the magic_quotes_gpc setting. Based on this setting, I may or may not need to use the addslashses function on input strings. So I had to write a new addslashes function that worked based on the value of get_magic_quotes_gpc(). This hassle made me wonder what the benefit of magic_quotes really was.

Are there other similar pitfalls that I need to be aware of?

Thanks for your input.
