drifterlrsc, I like your idea, but this simple code makes my home server crash (Win32, Apache
2.0.58, PHP 5.1.4). It happens when the string is shorter than $n. So I changed the code to work
right. Here is how it looks now:
<?php
function shorten($s,$n) {
if (strlen($s)<$n) {
exit;
}
$scan=0;
while($scan==0){
if(substr($s,$n,1)==' '){
$scan=1;
}else{
$n++;
}
}
echo substr($s,0,$n) . "...";
}
?>
Code below prevents function execution if the string is shorter than $n.
if (strlen($s)<$n) {
exit;
}
Excuse me for my bad English.
