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;


}
