Re: Truncate words in multiple paragraphs

Hi Richard, I quickly realized this and fooled with a few variations. Also have to take into account that the <br> or the <br /> get counted as 1 or 2 words respectively, and so the trim can end up in the wrong place. I've tried fiddling with counting the number of br's in the string and adding that to the truncation limit before the preg_split, but this is still not ideal. I'm going to have a look at your other suggestion too. Thanks for your thoughts :) verdon On 3-Feb-06, at 4:21 PM, Richard Lynch wrote:

This would work if you replace the <br /> with <br> -- Otherwise, it's too likely to break up "<br />" in the trim_text function and then you end up with: "start of string ... almost 255 words, blah blah blah<br" On Fri, February 3, 2006 11:25 am, John Meyer wrote:

Hi :) I am using the following function (that I found in the user comments on php.net manual) for trimming the number of words accepted via a form field // Truncation is by word limit, not character limit. So if you limit // to 255, then it will cut off a text item to 255 words, not 255 characters function trim_text ($string, $truncation=250) {

    $string = preg_split("/\s+/",$string,($truncation+1));
    unset($string[(sizeof($string)-1)]);
    return implode(' ',$string);

}

How about $string = nl2br($string); $string = trim_text($string); $string = str_replace("<br />","\n",$string); -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFD45Hzj60GAoLuoDkRAjSqAKCxvGlJmSCVHozWBDjjZnKMEZOfSwCfenVj lRSChtsMRqRnOYdZpk5YQ0c= =Dnly -----END PGP SIGNATURE----- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
