The reason for this is as follows: - * - * The PHP docs say: - * "The third argument charset defines character set used in conversion." - * - * I suspect PHP's htmlspecialchars() is working at the byte-value level and - * thus _needs_ to know (or asssume) a character set because the special - * characters to be replaced could exist at different code points in - * different character sets. (If indeed htmlspecialchars() works at - * byte-value level that goes some way towards explaining why the - * vulnerability would exist in this function, too, and not only in - * htmlentities() which certainly is working at byte-value level.) - * - * This replacement function however works at character level and should - * therefore be "immune" to character set differences - so no charset - * parameter is needed or provided. If a third parameter is passed, it will - * be silently ignored. - * - * In the OUTPUT there is a minor difference in that we use ''' instead - * of PHP's ''' for a single quote: this provides compatibility with - * get_html_translation_table(HTML_SPECIALCHARS, ENT_QUOTES) - * (see comment by mikiwoz at yahoo dot co dot uk on - * http://php.net/htmlspecialchars); it also matches the entity definition - * for XML 1.0 - * (http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_Special_characters). - * Like PHP we use a numeric character reference instead of ''' for the - * single quote. For the other special characters we use the named entity - * references, as PHP is doing. - * - * @author {@link http://wikkawiki.org/JavaWoman Marjolein Katsma} - * - * @license http://www.gnu.org/copyleft/lgpl.html - * GNU Lesser General Public License - * @copyright Copyright 2007, {@link http://wikkawiki.org/CreditsPage - * Wikka Development Team} - * - * @access private - * @param string $string string to be converted - * @param integer $quote_style - * - ENT_COMPAT: escapes &, <, > and double quote (default) - * - ENT_NOQUOTES: escapes only &, < and > - * - ENT_QUOTES: escapes &, <, >, double and single quotes - * @return string converted string - * @since 1.0.7.18 - */ - function hsc($string, $quote_style = ENT_COMPAT) { - // init - static $aTransSpecchar = array( - '&' => '&', - '"' => '"', - '<' => '<', - '>' => '>', - - //This fix is related to SF#1923020, but has to be applied - //regardless of actually highlighting symbols. - - //Circumvent a bug with symbol highlighting - //This is required as ; would produce undesirable side-effects if it - //was not to be processed as an entity. - ';' => '<SEMI>', // Force ; to be processed as entity - '|' => '<PIPE>' // Force | to be processed as entity - ); // ENT_COMPAT set - - switch ($quote_style) { - case ENT_NOQUOTES: // don't convert double quotes - unset($aTransSpecchar['"']); - break; - case ENT_QUOTES: // convert single quotes as well - $aTransSpecchar["'"] = '''; // (apos) htmlspecialchars() uses ''' - break; - } - - // return translated string - return strtr($string, $aTransSpecchar); - } - - /** - * Returns a stylesheet for the highlighted code.
