Insert Arabic values in SqlServer 2019 using php

Question

I want to insert arabic values, so i used this syntax :

$sql = "
    insert into sdka_creation (creation_time, sdka_for, creator_ip)
    values ('$creation_time',N\'$name\', '$creator_ip')
";

// or N"$name"

this gives me this error :

Fatal error: Uncaught TypeError: sqlsrv_rows_affected(): Argument #1 ($stmt) must be of type resource, bool given in C:\xampp\htdocs\quran\go.php:443 Stack trace: #0 C:\xampp\htdocs\quran\go.php(443): sqlsrv_rows_affected(false) #1 {main} thrown in C:\xampp\htdocs\quran\go.php on line 443

and other time :

$fnmae = N'$name';
$sql = "
    insert into sdka_creation (creation_time, sdka_for, creator_ip)
    values ('$creation_time','$fname', '$creator_ip')
";

this gives me synatx error :

Syntax error: unexpected token ''$name''

how could be solved ?

Note : db type is nvarchar

summary (all of these errors) :

 $sql = "
     insert into sdka_creation (creation_time, sdka_for, creator_ip)
     values ('$creation_time',N\'$name\', '$creator_ip')
 ";

and :

$fnmae = N'$name';
