Description:
In “Read more” segments, you often need to cut the text to a length and add ‘…’ at the end. This can be a bit tricky when the limit falls on a special character.
Solution:
We can use mb_substr() instead, and first decode the text and set the “UTF-8″ charset:
$length = 40;
$padding = ‘…’;if (strlen($fullDescription) > ($length + 3)) {
$shortDescription = html_entity_decode($fullDescription);
mb_internal_encoding(“UTF-8″);
$shortDescription = mb_substr($shortDescription, 0, $length);
$shortDescription .= $padding;
}
This will decode all entities into their natural symbol and make sure they are interpreted as one character.
