note 44969 added to function.substr

This function is a rough and ready hack to take a string and trim it to a certain word length. A trailing ellipsis is added if the string is truncated. If the number of words in the string is shorter than the specified length, the string is returned unaltered. <? ## Take a sentence or group of words and trim to a defined word length with closing ellipis (...) ## ## $string (string) The string to truncate ## $length (int) The maximum number of words to output function trim_words($string,$length) { $words = explode(" ",$string); if (count($words >= $length)) { $trimmed = ""; for ($i = 0; $i < $length; $i++) { $trimmed .= $words[$i]." "; } $trimmed .= "..."; return($trimmed); } else { return($string); } } ?> ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+44969 Delete -- http://master.php.net/manage/user-notes.php?action=delete+44969&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+44969&report=yes Search -- http://master.php.net/manage/user-notes.php
