Basic PHP/ASP Functions Comparison
PHP and ASP are amongst the most widely used programming languages online and generally just knowing one will get you by all the way.
There are some people however, who would like to know both for various reasons I won’t bore you with but this list will eb a great starting point for anyone who wished to do so.
NOTE: By ASP, I mean ASP (VB), not ASP (C) or ASPX

Conclusion
It’s always good to know the basic syntax of a variety of languages in your field just to get you by those odd task’s that appear once in a while.
I wish I had seen this before.
I have seen this before, Dave Stopher SEO. I would have thought you would have too.
This is great. I work on ASP sites now and again; this is a brilliant reference for me and others.
ASP 3 is ten years old and discontinued. Odd choice for comparison.
Thanks for the feedback Anders. It’s actually been quite some time since I put this list together and thought it would make a good blog post and may be useful to some out there!
