note 46785 added to function.htmlentities

Regarding the two great function posted by pinkpather and webwurst; one to encode xml entities, the other to encode only the entities of a string not already encoded. I've combined these two. And IMHO made a small improvement by making the translation table static: <?php function xmlentities($string, $quote_style=ENT_QUOTES) { static $trans; if (!isset($trans)) { $trans = get_html_translation_table(HTML_ENTITIES, $quote_style); foreach ($trans as $key => $value) $trans[$key] = '&#'.ord($key).';'; // dont translate the '&' in case it is part of &xxx; $trans[chr(38)] = '&'; } // after the initial translation, _do_ map standalone '&' into '&#38;' return preg_replace("/&(?![A-Za-z]{0,4}\w{2,3};|#[0-9]{2,3};)/","&#38;" , strtr($string, $trans)); } ?> Here's the snippet of code I'm testing with: <?php echo "<p>Testing xmlentities...</p>"; $strings[] = "No entities here."; $strings[] = "<b>bold</b>"; $strings[] = "Got style? Try K & R."; echo "<ul>"; foreach ($strings as $string) { echo "<li>Original string: ".htmlentities($string)."</li>\n"; echo "<li>Encoded once: ".htmlentities(xmlentities($string))."</li>\n"; echo "<li>Encoded twice: ".htmlentities(xmlentities(xmlentities($string)))."</li>\n"; } echo "</ul>"; ?> ---- Manual Page -- http://www.php.net/manual/en/function.htmlentities.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+46785 Delete -- http://master.php.net/manage/user-notes.php?action=delete+46785&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+46785&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+46785&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+46785&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+46785&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+46785&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+46785&report=yes Search -- http://master.php.net/manage/user-notes.php
