If you're going to be using Perl in depth every day, this module covers some golden nuggets and extra syntaxes that you might have been looking for. There's a rule of thumb with Perl Ð "If you're finding something more difficult than you expected, there's probably an easier way".

Well House Consultants specialise in training courses in Python, Perl, PHP, and MySQL. We run Private Courses throughout the UK (and beyond for longer courses), and Public Courses at our training centre in Melksham, Wiltshire, England. It's surprisingly cost effective to come on our public courses - even if you live in a different country or continent to us.

We have a technical library of over 600 books on the subjects on which we teach. These books are available for reference at our training centre. Also available is the Opentalk Forum for discussion of technical questions.
