Filtering a string

[MrEyes]

Lets say I have the following string:


this is some text

this is a wibble of random length

this is some more text


I need to filter out everything between, and including, and . So I would end up with the following:



this is some text

this is some more text


Does anybody know how to do that?

function stripos($haystack, $needle, $offset=0) {
return strpos(strtoupper($haystack), strtoupper($needle), $offset);
}

That will get the position of a string in another string. After that use substr

duh!! Wood for the trees and all that :)

Anyway, that works... However

I am currently working on something that will add quote functionality into vBulletin social group discussions (why this wasn't added is a mystery to me). The reason for the question is that I need to strip out quotes within the quoted post. This is something that occurs when a forum post is quoted so I am guessing that this filtering functionality already exists somewhere in the VB framework, but I will be damned if I can find it.

Does anybody know where it might be, as using the substr etc complicates things as the code will have to cater for all imaginable scenarios.

look for the functions in postreply.php or whatever it's called? I don't know specifically

strip_bbcode()
strip_quotes()

I think you're looking for those.
