preg_replace() Help

[Joseph Witchard]

Is there a list of what all the different operators used in a preg_replace() function mean/do?

modifires go after the last /
the syntax notes are the ones inside the /s

Can you explain that a bit more slowly? :o

[scragar]

all the preg functions use the same syntax BTW:
preg_match("/Pattern Syntax/Pattern Modifiers", $something)
as per labels on the link I gave above. the modifiers cover the whole expression, so i makes the entire regExp incase sensitive etc.

click regExp details in the pattern syntax page for the complete list, be warned, it's long.

Are you looking to match on a specific type of pattern (i.e. email, url, date, etc), if we knew that much we would be able to be a bit more helpful!

Well I'm going to be using it a lot for the script I'm writing. I'm trying to understand the theory, because I don't have a complete list of what I'm going to replace in my strings.

If the search is a simple string, you can use str_replace() instead.

I tried that. For right now, I'm just trying to build an editor that replaces certain code in a string and turns it into a hyperlink, bold text, etc. So, it has to be done with preg_replace().

Like such: PHP & BBCode (http://us.php.net/manual/en/intro.bbcode.php)?


Its not hard to install, if you know how to install PECL.. Which isn't TO hard.. Your webhost might already have it installed.. If your hosting your own site, you can try installing it yourself. See how to install on the link I provided.. I'm sure there is probably a BBCode class out there in the land of Google if you don't want to install anything on the server end.

Sure enough, a google search turned this up: Class that Parsed BBCodes for PHP (http://www.christian-seiler.de/projekte/php/bbcode/index_en.html)

While I still need to learn the logic of preg_replace(), that is going to help me a great deal. Thanks:D

I found some good info at: http://evolt.org/node/22700/
I don't know if this says it, but I always used ( ) in my preg_replace search string for what I wanted replaced.

Also, some good info here: http://www.regular-expressions.info
