PHP4 Friendly htmlspecialchars_decode


I needed to use the PHP function htmlspecialchars_decode( ) for a WordPress widget I am making. This function is built into PHP versions 5.1.0 and greater and is used to convert special HTML entities to characters. As defined, htmlspecialchars_decode( ) is the opposite of htmlspecialchars( ). Someone named Thomas commented on the PHP man page to point out a flaw in the definition. He also provides some code, which I have only modified slightly below to check function_exists( ).


if ( !function_exists('htmlspecialchars_decode') ){
    function htmlspecialchars_decode($string,$style=ENT_COMPAT)
    {
        $translation = array_flip(get_html_translation_table(HTML_SPECIALCHARS,$style));
        if($style === ENT_QUOTES){ $translation['''] = '\''; }
        return strtr($string,$translation);
    }
}

    I am not sure what you mean. The purpose of this function is to handle special characters in URLs, not plain text.
