Understanding Regular Expressions
Regular Expressions were something that were recently suggested to me during my 2nd VIVA presentation, with regards to form validation.
My initial encounter of the regular expression code was quite scary but then after doing some research I came across this article on sitepoint about Using Regular Expressions and PHP.
I have to admit, this article is very good and worthy of a read. It’s certainly going to influence my validation down the line and will be something I’m going to incorporate into my PHP regarding my major project (Slight Intention).
