PHP: properly truncating strings with “..”

Question

Currently, the method I use to truncate strings is: echo substr($message, 0, 30).\"..\";

How do I show the dots only in the case that the string has been tr

Answer 1

You could do:

echo strlen($message) > 30 ? substr($message, 0, 30) . '..' : $mssage;

Basically, it's like (but shorter):

if (strlen($message) > 30) {
    echo substr($message, 0, 30) . "..";
} else {
    echo $message;
}
