 I've got to somehow ignore the trailing period if it is present.

if ($s[strlen($s)-1] == '.'){
  $s = substr($s, 0, -1);
}

Wow, I was really glad you found that.  I had never heard of this  
before, but it looks like the solution.


However, my real life example still isn't working, even after adding  
what I think was the right look-ahead expression:


@(http://\S+)(?!\.)@   -- this still captures everything

@(http://\S+?)(?!\.)@-- this captures too little

Any ideas?  In any case, thanks for the article -- that was informative.

[PHP] wrapping anchor tags around a URL

2006-01-23 Thread Richard K Miller 
I wrote a little function to put anchor tags around a URL.  We're  
using it to make URL's in paragraphs of text linkable:


function link_the_links($s) {
return preg_replace('@(http://[^\s]+)@sm', 'a href=$1$1/a', $s);
}

Its only flaw (besides a goofy name) is that if a link comes at the  
end of a sentence, right before the period, the period ends up in the  
link, thus breaking the link.  I've got to somehow ignore the  
trailing period if it is present.


Any ideas?
