htmlspecialchars_decode

The example for "htmlspecialchars_decode()" below sadly does not work for all PHP4 versions. Quote from the PHP manual: "get_html_translation_table() will return the translation table that is used internally for htmlspecialchars() and htmlentities()." But it does NOT! At least not for PHP version 4.4.2. This was already reported in a bug report (http://bugs.php.net/bug.php?id=25927), but it was marked as BOGUS. Proof: Code: -------------------- <?php var_dump(get_html_translation_table(HTML_SPECIALCHARS,ENT_QUOTES)); var_dump(htmlspecialchars('\'',ENT_QUOTES)); ?> -------------------- Output: -------------------- array '"' => '&quot;' ''' => '&#39;' '<' => '&lt;' '>' => '&gt;' '&' => '&amp;' '&#039;' -------------------- This comment now is not to report this bug again (though I really believe it is one), but to complete the example and warn people of this pitfall. To make sure your htmlspecialchars_decode fake for PHP4 works, you should do something like this: <?php function htmlspecialchars_decode($string,$style=ENT_COMPAT) { $translation = array_flip(get_html_translation_table(HTML_SPECIALCHARS,$style)); if($style === ENT_QUOTES){ $translation['&#039;'] = '\''; } return strtr($string,$translation); } ?>  Br, Thomas

This should be the best way to do it. (Reposted because the other one seems a bit slower and because those who used the code under called it htmlspecialchars_decode_php4) <?php if ( !function_exists('htmlspecialchars_decode') ) { function htmlspecialchars_decode($text) { return strtr($text, array_flip(get_html_translation_table(HTML_SPECIALCHARS))); } } ?>

that works also with ä and " and so on. get_html_translation_table(HTML_ENTITIES) => offers more characters than HTML_SPECIALCHARS function htmlspecialchars_decode_PHP4($uSTR) { return strtr($uSTR, array_flip(get_html_translation_table(HTML_ENTITIES, ENT_QUOTES))); }
