note 96649 added to function.preg-replace

If you want to add simple rich text functionality to HTML input fields, preg_replace can be quite handy. For example, if you want users to be able to bold text by typing *text* or italicize it by typing _text_, you can use the following function. <?php function encode(&$text) { $text = preg_replace('/\*([^\*]+)\*/', '<b>\1</b>', $text); $text = preg_replace('/_([^_]+)_/', '<i>\1</i>', $text); return $text; } ?> This works for nested tags, too, although it will not fix nesting mistakes. To make this function more efficient, you could put the delimiters (* and _, in this case) and their HTML tag equivalents in an array and loop through them. ---- Server IP: 69.147.83.197 Probable Submitter: 97.119.215.41 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/96649 Del: integrated -- https://master.php.net/note/delete/96649/integrated Del: useless -- https://master.php.net/note/delete/96649/useless Del: bad code -- https://master.php.net/note/delete/96649/bad+code Del: spam -- https://master.php.net/note/delete/96649/spam Del: non-english -- https://master.php.net/note/delete/96649/non-english Del: in docs -- https://master.php.net/note/delete/96649/in+docs Del: other reasons-- https://master.php.net/note/delete/96649 Reject -- https://master.php.net/note/reject/96649 Search -- https://master.php.net/manage/user-notes.php
