Why I like PHP.
I am a PHP newbie but the following I think is important.
I use ASP at work and PHP in my other interests.
First my webserver people at work, god bless them are as dumb as a box of rocks. I don't mean that against their person, thats just the way it is. Many times when I want to do some ASP script that is useful to my department ( photography ) the script won't work because the webserver (MS) isn't configured correctly. ( hey I can do ASP includes; yippie ). If I need a serious database ( Access is a non starter for anything serious ) My next step is MS SQL or Oracle ( not an option in my situation ) The IT department is maybe not too open to anything that makes their job harder ( my situation only not a broad brush )
Now I have just started using PHP in my outside of work interests and you know what? I am yet to be limited by anything. The only roadblocks I encounter are based on my lack of experience.
So there you go. Not a total answer. But if you had to start a project today I think you first have to decide: " Do you want maximum growth room in case it gets big?" And you know what? If I had to, I would pay for PHP and MySQL if needed. So for me the price by itself doesn't mean much. I don't think I would use ASP if it were free, given what I know now.
BTW nice site Daynah. Looks very useful.
