[pLog-svn] r3433 - plog/trunk/class/view/admin

Here comes the example from php.net.

Maybe we can refer to this write our own replacement.

===========

Example 1. Convert HTML to text

<?php
// $document should contain an HTML document.
// This will remove HTML tags, javascript sections
// and white space. It will also convert some
// common HTML entities to their text equivalent.
$search = array ('@<script[^>]*?>.*?</script>@si', // Strip out javascript
                 '@<[\/\!]*?[^<>]*?>@si',          // Strip out HTML tags
                 '@([\r\n])[\s]+@',                // Strip out white space
                 '@&(quot|#34);@i',                // Replace HTML entities
                 '@&(amp|#38);@i',
                 '@&(lt|#60);@i',
                 '@&(gt|#62);@i',
                 '@&(nbsp|#160);@i',
                 '@&(iexcl|#161);@i',
                 '@&(cent|#162);@i',
                 '@&(pound|#163);@i',
                 '@&(copy|#169);@i',
                 '@&#(\d+);@e');                    // evaluate as php

$replace = array ('',
                 '',
                 '\1',
                 '"',
                 '&',
                 '<',
                 '>',
                 ' ',
                 chr(161),
                 chr(162),
                 chr(163),
                 chr(169),
                 'chr(\1)');

$text = preg_replace($search, $replace, $document);
?>
