Convert accents to HTML, but ignore tags

Question

The code below converts text for characters with accents. But it also converts the HTML tags which I would like to leave intact. How can I only convert accented characters and leave all other special characters intact? Thanks.

$temp = file_get_contents("file.html");
echo htmlentities($temp,ENT_NOQUOTES,'UTF-8');

Answer 1

htmlspecialchars() and htmlspecialchars_decode() will only encode/decode &, <, >, ' and "; you could thus use the latter to convert their entities back to their HTML special characters:

echo htmlspecialchars_decode(htmlentities($temp, ENT_NOQUOTES, 'UTF-8'), ENT_NOQUOTES);
