htmlentities
The following replacement for PHP 4 is a little more complete, as the quote_style is taken into account as well:
if (!function_exists("htmlspecialchars_decode")) {
function htmlspecialchars_decode($string, $quote_style = ENT_COMPAT) {
return strtr($string, array_flip(get_html_translation_table(HTML_SPECIALCHARS, $quote_style)));
}
}
htmlspecialchars_decode
(PHP 5 >= 5.1.0)

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)));
}
}
?>

Here is how you can get this function in php < 5.1, just make sure this function is before you try and call the function.
if (!function_exists('htmlspecialchars_decode')) {
function htmlspecialchars_decode($str, $options="") {
$trans = get_html_translation_table(HTML_SPECIALCHARS, $options);
$decode = ARRAY();
foreach ($trans AS $char=>$entity) {
$decode[$entity] = $char;
}
$str = strtr($str, $decode);
return $str;
}
}

The code supplied by or-k at or-k dot com (14-Sep-2005 09:15) is better served using html_entity_decode() for PHP>=4.3.0.
geoffers@gmail (14-Jul-2005 01:38) offers the best htmlspecialchars_decode() for php4 users.

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)));
}

[Update of previous note, having noticed I forgot to put in quote style]
PHP4 Compatible function:
<?php
function htmlspecialchars_decode_php4 ($str, $quote_style = ENT_COMPAT) {
return strtr($str, array_flip(get_html_translation_table(HTML_SPECIALCHARS, $quote_style)));
}
?>

?>
