chopSent is very simplistic script/function intended to limit the character output of a given string and emphasize that the string does indeed continue, however input source is NOT limited, so use your imagination.

<?php

                                function chopSent($varb, $num) { 

                                    $dNum = intval($num); 

                                    if (strlen($varb) > $dNum) { 

                                        $nVarb = substr($varb, 0, $dNum); 

                                        $nVarb .= '...'; 

                                    } 

                                    elseif(strlen($varb) < $dNum) { 

                                        $nVarb = $varb; 

                                    } 

                                    return $nVarb; 

                                } 

                                // Usage of function

                                $theSent = chopSent($theSent, 55);   

                                echo $theSent; 
 ?>
