I am tring to create a new table into the database if the table name given is not present in database using Php .
This is the code that I am using .

  $conn = mysql_connect($dbhost, $dbuser, $dbpass);
    if(!$conn)
    {
            die('Failed to connect to server: ' . mysql_error());
            exit;
    }
    $db_selected = mysql_select_db($dbname);
    if(!$db_selected)
    {
           $db_selected = " CREATE DATABASE $dbname ";
    }
    $usertb1 = mysql_query("select 1 from $usertb LIMIT 1");
    if( $usertb1 !== FALSE )
    {
           $sql = "CREATE TABLE IF NOT EXISTS $usertb ( uid INT(20) AUTO_INCREMENT UNIQUE KEY NOT NULL,name VARCHAR(40),email varchar(40) PRIMARY KEY NOT NULL)";
    }
