Question

I don’t know what is going on with this but htmlentities() function is not working!

Here is what i have done

(the bottom code work correctly but htmlentities() does not convert quotes to html code! for example ” should be change to some html5 code!

$term = "'" . addslashes($_GET['search_term']) . "%'";
if(!isset($term{2})){
    exit();
}

$query = $db->query('SELECT customerID, fullName, dID, birthYear, homeAddress, ID, DATE_FORMAT(idIssue, "%d-%m-%Y") AS idIssue, DATE_FORMAT(idExp, "%d-%m-%Y") AS idExp, phone
                     FROM customers WHERE (fullName LIKE '.$term.' ) LIMIT 0,10');



while( $row = $query->fetch_assoc()){

    foreach($row as $key => $value){
        $arr[$key] = htmlentities(stripslashes($value), ENT_QUOTES);
    }
    $json[] = $arr;
}

echo json_encode($json);

Answer 1

The value you pass to json_encode() must be UTF-8 encoded data.
Therefore, before you run json_encode, use utf8_encode.

Example:

 $arr[$key] = htmlentities(stripslashes(utf8_encode($value)), ENT_QUOTES);
