Why would:

$stringPadding = ' ...';

not be used in

return substr_replace($string, $stringPadding, $maxLength - 3 ,
strlen($string));

which is part of a function to chop strings that are too long? If I use:

return substr_replace($string, " ...", $maxLength - 3 , strlen($string));

it works perfectly well. PHP 4.2.3.

Thanks for any input.

John
