PHP function to convert HEX char codes to display equivalent

I am working on some PHP code to identify HEX character codes in a string and convert them to their "as seen on screen" equivalent. Mainly, there HEX codes are for accented characters like é, ç and so on.

For example, I am receiving a string like this:

$str = "caf&#xe9s"; - NOTE there is a semicolon after the 9 (i had to remove it to stop this text editor converting it!

The HEX part of the string is &#xe9 (again with semicolon at end) - and I am needing to convert that to its "as seen on screen" equivalent, in this case "é". So the converted string would be "cafés".

The following PHP code works, but I have to write one for each HEX code, and there are scores of them.

$keywords = str_replace("&#xe9","é",$keywords); [again the needle part has a semicolon]

Can anyone suggest an existing PHP function that can scan any string for known HEX codes and convert it to the display equivalent?

I am working in UTF8 otherwise.

Thanks for your consideration, sorry if my terminology sounds amateur.

This will convert HTML entities into their associated char

$keywords = html_entity_decode($keywords);
