I mean if I have a 2 page content - just I want to display only 4 lines
having 200 letters then follows the content with "....." at the end of

Can anybody help in this regards,
Thanks in advance


I wrote this function to do just that.  It has the added feature that it
truncates on a space rather than the middle of the word.

$string is the long string to truncate
$length is the maximum truncated length
$url is the URL you should go to to see the whole paragraph

<?php
function truncate($string,$length,$url){
$string=trim($string);
if(strlen($string)>$length){
$string=substr($string,0,$length);
$n=0;
while(substr($string,-1)!=chr(32)){
$n++;
$string=substr($string,0,$length-$n);
}
$string=trim($string)."... <a href='$url'><em>more</em></a>";
} return $string;
} 

//example usage
 echo truncate("the quick brown fox jumps over the lazy
dog",35,"anyurl");
 ?>


Shorter :)

function trancate($string,$length) {
  $string = substr(trim($string),0,$length);
  $string = substr($string,0,strrpos(trim($string)," "));
  return "$string...";
}
.
