Would I be missing much if I stopped trying to learn Perl well enough to use for
spidering, screen scraping etc. and converted over to PHP ? I am looking to do
all, or at least most of the hacks decribed in the books 'Spidering Hacks' and
'Perl & LWP'. I am familiar with the book 'Webbots, Spiders, and Screen Scrapers: A
Guide to Developing Internet Agents with PHP/CURL' Would anyone know of any other
sources of info related to this kind of thing ?

Some pointers (maybe you know this already)
If you need regular expressions, and I expect you will be using them, be
sure to use the PCRE flavor in PHP. (Perl Compaticle Regex)
The functionnames all start with preg_
The functions can be found here:
Using preg will safe you a headache when using Perl style regex.
If you use a database to store the information, I think your best bet is
using PDO to interface with the database of your choice, be it MySQL or
Postgresql, etc. (I am a fan of Postgresql)
A lot of info can be found here:
Hope this helps a little.
Good luck.
