How to json_encode array with french accents?

Question

I have an array item with a French accent ([WIPDescription] => Recette Soupe à lOignon Sans Boeuf US). The data is being properly pulled from the database (mysql).

Answer 1

I found this to be the easiest way to deal with it

echo json_encode($array, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);

JSON_PRETTY_PRINT - makes is readable
JSON_UNESCAPED_UNICODE - encodes characters correctly
JSON_UNESCAPED_SLASHES - gets rid of escape slash '\'
also notice that these option are separated by a pipe '|'

Answer 2

$json = utf8_encode($string);

$json = json_decode($json);

Answer 3

json_encode only wants utf-8. Depending on your character set, you can use iconv or utf8_encode before calling json_encode on your variable. Probably with array_walk_recursive.

As requested, an unfinished way to alter an array, with the assumptions that (1) it doesn't contain objects, and (2) the array keys are in ascii / lower bounds, so can be left as is:

$current_charset = 'ISO-8859-15';//or what it is now
array_walk_recursive($array,function(&$value) use ($current_charset){
     $value = iconv('UTF-8//TRANSLIT',$current_charset,$value);

});

Answer 4

Per the PHP docs

This function only works with UTF-8 encoded data.

Answer 5

<? 

$sql=mysql_query("SELECT * FROM TABLE...");

while($row=mysql_fetch_array($sql))
{
    $output[]=array_map("utf8_encode", $row);
}
print(json_encode($output));
mysql_close();

?>

Answer 6

Another solution would be to use htmlentities or utf8_encode before using json_encode to pass the encoded char

like this:

   $array = array('myvalue' => utf8_encode('ééàà'));
   return json_encode($array);

Or using htmlentities :

   $array = array('myvalue' => htmlentities('ééàà'));
   return json_encode($array);
