PHP Formatting

joad

Have been working on some PHP code and trying to implement the below code on a forum, and has generally worked okay when a poster is just posting their post only, BUT, when they're also quoting another users post within theirs, without apparently going against any of the coding below, it gives the error message as if someone has posted one of the below? Is it the

code that appears when quoting someone elses post ?
          if (preg_match('/(http|www|.com|.es|.co.uk|.info|.org)/i', request_var('message', '', true)))  
But,with the .com in the code, it's also picking up on the words command, competition etc - is there any way that it can just pick up on the .com - (only if it has the dot as the prefix)

a dot (.) is a reserved character to mean "anything" - use a \ before it as follows:

if (preg_match('/(http|www|\.com|\.es|\.co\.uk|\.info|\.org)/i', request_var('message', '', true)))

\b means word boundary, so you might consider (or try) this, I have not tested it:

Escape the dot since a dot matches either any character or mostly any character.

note to self: don't leave tabs open for too long without refreshing them .

Many thanks to you both - the great help here is always appreciated. I tried the first example and it worked, would there be any benefit in trying the 2nd example above with the boundary?

http\b

would mean http followed by any of several "word boundary characters", such as various horizontal and vertical whitespace characters, as well as (at least) . , ; ! ?
It's possible that there are several other boundary characters that I've missed. See php's preg documentation. If the characters in question are not listed there, you could create a little script to check which are treated as word boundaries, for example ' and ".

The question is wether any of those should be allowed to follow http or not.
