HTMLPurifier_AttrDef_HTML_Class::filter (   $tokens,   $config,   $context  )

protected

Template method for removing certain tokens based on arbitrary criteria.

Note

If we wanted to be really functional, we'd do an array_filter with a callback. But... we're not.

Reimplemented from HTMLPurifier_AttrDef_HTML_Nmtokens.

Definition at line 17 of file Class.php.

References $config, and $ret.

                                                          {
        $allowed = $config->get('Attr.AllowedClasses');
        $forbidden = $config->get('Attr.ForbiddenClasses');
        $ret = array();
        foreach ($tokens as $token) {
            if (
                ($allowed === null || isset($allowed[$token])) &&
                !isset($forbidden[$token]) &&
                // We need this O(n) check because of PHP's array
                // implementation that casts -0 to 0.
                !in_array($token, $ret, true)
