Question

I have trouble finding a solution for the following problem:

I have a lot of special characters on the website that when I run them through htmlentities();

you get all the special characters converted to HTML entities:

£ => £
" => "
 => Â
....

But what I actually need is the Decimal version of that encoding:

£ => £
" => "
 of(Â) => À
  =>  

Is there a function that already exists that would solve this issue without doing this manually with a replace?

Answer 1

Something like the following?

function htmlnumericentities($str){ 
  return preg_replace('/[^!-%\x27-;=?-~ ]/e', '"&#".ord("$0").chr(59)', $str); 
} 

function numericentitieshtml($str){ 
  return utf8_encode(preg_replace('/&#(\d+);/e', 'chr(str_replace(";","",str_replace("&#","","$0")))', $str)); 
} 

echo (htmlnumericentities ("Ceci est un test : & é $ à ç <")); 
echo ("<br/>\n"); 
echo (numericentitieshtml (htmlnumericentities ("Ceci est un test : & é $ à ç <")));
