Php Solutions
Solution 1 - Php
If you use htmlentities() to encode, you can use html_entity_decode() to reverse the process:
html_entity_decode()
>Convert all HTML entities to their applicable characters. > >html_entity_decode() is the opposite of htmlentities() in that it converts all HTML entities in the string to their applicable characters.
e.g.
$myCaption = 'áéí';
//encode
$myCaptionEncoded = htmlentities($myCaption, ENT_QUOTES);
//reverse (decode)
$myCaptionDecoded = html_entity_decode($myCaptionEncoded);
Solution 2 - Php
You want to look at html_entity_decode and worry about which charset you should be using (probably ISO8859-1).

string html_entity_decode ( string $string [, int $quote_style = ENT_COMPAT [, string $charset = 'UTF-8' ]] )
