REGEX and the corresponding LANGUAGES? your advice needed?

[bilis_money]

Ok, now i know
that REGEX is very widespread.

REGEX with Java or with VBscript, or with MySQL, or with PYTHON, or with PERL, or with PHP and etc....

Now my questions are.
What are differences between these REGEX with its corresponding languages.
How do they differ each other?
Are they are all the same?
Or they don't have the same bult in function on its languages?
Are there relativeness between these languages about the REGEX?
Or relationships?

Any nice advice are welcome and must be appreciated a lot.


Thanks!

You need to pick up [url=http://www.regex.info]Mastering Regular Expressions[/url] if you're that concerned. They differ in terms of engines and syntax. To my knowledge, they all have the basics in common, such as *, ^, $, and [...]; things change beyond that.

Thanks [b]Effigy![/b]

I notice that you know a lot about REGEX, what are the best books that you can recommend?

How about "Mastering REGEX exclusive for PHP only", what do you recommend [b]effigy?[/b]


Thanks again for you kind help!

My recommendations are in my signature. There are numerous web resources and the only book that I can recommend, I already have. [url=http://www.regex.info]Mastering Regular Expressions[/url] is great. It will probably have more information that you need (how the engines actually work, unicode support, etc.), but it does a good job of getting you to think in terms of regex and there are many examples. The meat of the examples (outside of the language-specific sections) are in Perl, but: (1) this is expected since Perl pushed the envelope with them, and as a result many other languages, including PHP, have PCRE libraries; and (2) they are kept simple as far as understanding Perl is concerned.
