Yeah, well I've been programming in PHP since PHP/FI, but I did learn Perl first. And before that I was using sed, awk and grep etc. So I came to the language with a fair grasp of regexps. I'd bet, if you learned the core of PHP in 5 minutes, you must have been reasonably familiar with other procedural languages first. Experience which you can't carry across to regular expressions. OK, they're maybe not the most intuitive of constructs, but structurally they're a lot more simple than a full blown programming language. * No loops. * No functions. * No recursion. * No variable types. * The simplest possible conditionals. I don't believe they're *that* hard to learn, once you get beyond the line-noise syntax. Incidentally, with the PCRE library, you can even use the POSIX type character classes instead of the Perl syntax if you find them easier to understand ([[:digit:]] instead of \d, [[:word:]] instead of \w etc). Although I don't think that's documented in the manual. -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
