SitePoint PHP Blog:
The Joy of Regular Expressions [1]
Sep 26, 2006 @ 08:02:45

Sometimes, it's just not enough to sit and try to teach theory about something in programming - it's better to just jump right in and take things as they come. That's what Harry Fuecks thinks, at least in his latest post on the SitePoint PHP Blog - a look at the "Joy of Regular Expressions".

He does go over a bit of the theory and why they are so invaluable, but it's a short section before he gets to the heart of the article - working with regular expressions for:

  • positive matching
  • matching all instances in a given string
  • finding an exact match
  • matching the start of a string
  • validation of the contents of a string
  • checking the length of a string
There's simple examples included for each of the items to help you get an idea of how they'd work.
