RegEx

ReSpawN · 04-30-2008, 08:01 PM

Doh. Me again.

Well, been exploring the fields of RegExes and I do not understand anything of it to be exact. I am trying to write a RegEx to filter out a string like {MYTEXT} and replace it while I am doing it.

I don't know where to start off actually. Help?

Regular-Expressions.info - Regex Tutorial, Examples and Reference - Regexp Patterns
Regular Expressions Cheat Sheet - Cheat Sheets - ILoveJackDaniels.com

and finally,

preg_match()
preg_replace()

For "mytext", if that was the literal string, you could

echo preg_replace("~(mytext)~", "newtext", $szString);

...for a real basic example.

By the way, you just want to rid of some text? lol just do

PHP Code:


			

$string = preg_replace('/My text/','ttt',$string);

which replaces My text with ttt in $string;

Nah, some books are great.

apress are my favourite so far. Everywhere I went looking for books, all I could find were the same old PHP books from various publishers - you know the ones, this is a variable, this is a control structure, this is how you write a basic little form handler script, and aren't you glad you read 500 pages so you could learn the same thing you could learn from the manual in a fifth of that? I went looking on Amazon and found apress/Matt Zandstra's PHP Objects, Patterns, and Practice, and Pro PHP, two books I would highly recommend, and I'm not even done reading them yet. Some excellent reference, examples, and a lot of things the manual doesn't go anywhere near covering.

Lol, I've tried books of many types, including design patterns, C++, Java, Python, Pro Ajax, and more..

They were alright, they had some good tutorials, but in the end the internet won my vote. lol

+1 for Mastering Regular Expressions by O'Reilly

Great book, indeed. I've actually managed to write it from the beginning to the end and it definitely cleared some things up for me.

Take my word for it. I learn most stuff from internet resources as well, however Mastering Regular Expressions is a book that goes way more in-depth than anything I ever read about regular expressions online.

Glad you liked it too. By the way, you managed to write it?
