How can I specify the length of the string more precisely?

I am using this to shorten long titles:

<?php

$title = $row['adtitle'];
if (strlen($title) > 50) {
    $title = substr($title, 0, 50).'...';
}
echo $title;

?>

Code (markup):

The thing is it shortens them this way:

Selling housing in OH. Stop by to check it ou...

Make money working from home. Best opport...

I want it to shorten them right before the last word, so that it would look like this:

Selling housing in OH. Stop by to check it...

Make money working from home. Best...

Any ideas how to do that?

Thanks!

Try this:

$title = $row['adtitle'];
if (strlen($title) > 50) {
    $title = preg_replace('~\s+\S+$~', '', $title);
    $title = $title."...";
}
echo $title;

Working great. Thank you so much!

 

Somebody on another forum pointed out that one line was missing (which probably you just forgot to add):

<?php

$title = $row['adtitle'];
if (strlen($title) > 50) {
    $title = substr($title, 0,50);
    $title = preg_replace('~\s+\S+$~', '', $title);
    $title = $title."...";
}
echo $title;

?>

Nonetheless, your code is working well too.
