note 120007 added to function.wordwrap

Some people use wordwrap as long text cutter. I have a slightly different approach for that. The function does not wrap the text, but returns the position where to cut. It preserves HTML tags (does not count them) and strips br tags and whitespaces at the end. I am looking into a way prevent HTML tags corruption which can happen at this time and also support BB tags like code and quote, so that they won't be counted as well. When I do, I'll post an updated version of the code. <?php function txtcut($string, $length) { $tag = false; $chars = 0; $position = 0; $split = str_split($string); foreach ($split as $char) { $position++; if ($char == "<") { $tag = true; continue; } if ($char == ">") { $tag = false; continue; } if ($tag == true) { continue; } $chars++; if ($chars >= $length) { if ($char == " " || $char == "\r" || $char == "\n") { $position--; break; } } } if ($position == strlen($string)) { return strlen($string); } else { $string = substr($string, 0, $position); if (substr($string, -4, 4) == "<br>") { $string = rtrim(substr($string, 0, -4)); } return strlen($string); } } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 109.173.40.126 ---- Manual Page -- http://php.net/manual/en/function.wordwrap.php Edit -- https://master.php.net/note/edit/120007 Del: integrated -- https://master.php.net/note/delete/120007/integrated Del: useless -- https://master.php.net/note/delete/120007/useless Del: bad code -- https://master.php.net/note/delete/120007/bad+code Del: spam -- https://master.php.net/note/delete/120007/spam Del: non-english -- https://master.php.net/note/delete/120007/non-english Del: in docs -- https://master.php.net/note/delete/120007/in+docs Del: other reasons-- https://master.php.net/note/delete/120007 Reject -- https://master.php.net/note/reject/120007 Search -- https://master.php.net/manage/user-notes.php
