I wanted to ask that in a php script of mine which I am accessing through an ajax request, I am returning json data ( converted from an array ) as such

 echo json_encode($row_array);

I get this data in jquery and display it in a form. Do i need to apply htmlspecialchars / htmlentites before returning the data?

Is do then whats the correct way to do it? The following code gives me an error:

echo htmlentities(json_encode($row_array));

Thanking you Imran
