$sql = "INSERT INTO mesaj (uid,ipi,yorum,tarih) VALUES ('$uid','$ipi','$comment','$todayis') ";
$result = $conn->query($sql);
@mysql_query("SET NAMES 'utf8'");
}
I have inserting some chracters to my database like ç,ö,ş,ü,ğ
I heard that @mysql_query("SET NAMES 'utf8'"); make things right

but I'm not sure where to put the code?
is it correct to write it like above?

Short answer, "no" -- instead use something like the methods documented here:

See Character Sets in MySQL and also Using UTF-8 with PDO

First you should leave mysql (is deprecated: http://php.net/manual/en/migration55.deprecated.php) and switch to mysqli.

That done, you should set utf-8 for the whole database when you establish the connection:

$conn = new mysqli($db_host, $db_username, $db_password, $db_name);
$conn->set_charset("utf8mb4");

NEVER write anything that uses the MySQL extension again!

Some help on migrating from the obsolete MySQL extension to one of the supported extensions is available in this article:
https://www.experts-exchange.com/articles/11177/PHP-MySQL-Deprecated-as-of-PHP-5-5-0.html

But that said, there is a little more to it than just changing the DB character set.  You need consistency across all parts of the platform, including the database, the PHP scripts, and the HTML document.  The code examples in the Unicode article are all tested and seem to work well.

is it better in this way?

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "INSERT INTO mesaj (uid,ipi,yorum,tarih) VALUES ('$uid','$ipi','$comment','$todayis') ";

if (mysqli_query($conn, $sql)) {
    echo "Mesajınız alınmıştır";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

Yes, it is better to use MySQLi, and not MySQL.  But the code you posted above does not specify UTF-8.  You can find all the details in the article!
https://www.experts-exchange.com/articles/11880/Unicode-and-Character-Collisions.html

Try it like this:
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// SET THE CHARACTER SET
mysqli_set_charset($conn, "utf8mb4");

$sql = "INSERT INTO mesaj (uid,ipi,yorum,tarih) VALUES ('$uid','$ipi','$comment','$todayis') ";

if (mysqli_query($conn, $sql)) {
    echo "Mesajiniz alinmistir";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
