cutting strings

alexgeek · #1 Aug 25th, 2007, 01:17

I would like to have a string be cut off if it is over a certain amount of characters and add ".." to the end of the string.
I think what I need is similiar to wordwrap but instead of starting a new line it just cuts the rest off.
sorry if that isn't clear enough.
cheers

substr()

Help needed again....
is there anyway to do this without breaking html tags?
and close any if they are left open?
google was not my friend today

Alex ... Google wasn't being your friend because there is no easy way

. It's easy enough to tell whether you're within a particular tag or not, but to tell whether you're between an open and a close when you chop something is trickier, especially if you're not using well-formed HTML.

I can across a need to truncate a piece of HTML that I had gathered as a result of a search, and be able to display it robustly. Similar to your requirement, I think? I took the approach of replacing all tags with " ... " and then using a regular expression rather than substr to ensure that the remaining snippet was a few characters shorter than my maximum if necessary, but always broken at a white space. See http://www.wellho.net/net/search.php4?search=friend for an example of what you can achieve through this approach.

not sure what exactly your trying to do, but play around with this:

PHP: Select all


if ($string != "<html>") {
$newstring = substr_replace($string,"",-4);
echo $newstring."..";
}

I think I might just strip all tags :/
