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");
?>
