While having the option to append a string to the end is nice, you can run into the problem of having a space between the append if the width is truncated after a space. I find something like this to be more attractive in the output, although messy in the code.

rtrim(mb_strimwidth($string, 0, 24))."..."

<?php
function strimwidthCenter( $value, $length = 40 ) {
   
$valueEncoding = mb_detect_encoding( $value, 'auto', true );
    if (
$length >= mb_strwidth( $value, $valueEncoding ) ) {
        return
$value;
    }
   
$limited = '';
   
$firstWidth = ceil( $length/2 );
   
$secondStart = mb_strwidth( $value, $valueEncoding ) - ( $length - $firstWidth );
   
$secondWidth = $length - $firstWidth +1;
   
$limited = mb_strimwidth( $value, 0, $firstWidth, '...', $valueEncoding ) . mb_substr( $value, $secondStart, $secondWidth, $valueEncoding );
    return
$limited;
}

I had a problem (as in another comment) with a space being between the trailing dots and the subject being truncated. Here's how I fixed it:

<?php str_replace( " .", ".", mb_strimwidth( $subject, 0, 30, "..." ) ); ?>
