Python’s constructed-successful slicing capabilities brand drawstring truncation simple:
def truncate_string(matter, max_length): if len(matter) > max_length: instrument matter[:max_length] + "..." instrument matter
JavaScript
JavaScript provides akin performance utilizing the piece() methodology:
relation truncateString(matter, maxLength) { instrument matter.dimension > maxLength ? matter.piece(zero, maxLength) + "..." : matter; }
Java
Java’s substring() technique permits for exact drawstring manipulation:
national static Drawstring truncateString(Drawstring matter, int maxLength) { instrument matter.dimension() > maxLength ? matter.substring(zero, maxLength) + "..." : matter; }

//The elemental interpretation for 10 Characters from the opening of the drawstring $drawstring = substr($drawstring,zero,10).'...';
Replace:
Primarily based connected proposition for checking dimension (and besides making certain akin lengths connected trimmed and untrimmed strings):
$drawstring = (strlen($drawstring) > thirteen) ? substr($drawstring,zero,10).'...' : $drawstring;
Truthful you volition acquire a drawstring of max thirteen characters; both thirteen (oregon little) average characters oregon 10 characters adopted by ‘…’
Replace 2:
Oregon arsenic relation:
relation truncate($drawstring, $dimension, $dots = "...") { instrument (strlen($drawstring) > $dimension) ? substr($drawstring, zero, $dimension - strlen($dots)) . $dots : $drawstring; }
Replace three:
It’s been a piece since I wrote this reply and I don’t really usage this codification immoderate much. I like this relation which prevents breaking the drawstring successful the mediate of a statement utilizing the wordwrap relation:
relation truncate($drawstring,$dimension=one hundred,$append="…") { $drawstring = trim($drawstring); if(strlen($drawstring) > $dimension) { $drawstring = wordwrap($drawstring, $dimension); $drawstring = detonate("\n", $drawstring, 2); $drawstring = $drawstring[zero] . $append; } instrument $drawstring; }
