$con = mysql_connect ($servername, $username, $password, $database) or die('cant connect server');
mysql_select_db('test',$con);

// put in a string
$matstring = implode("','",$data);
$matstring="".$matstring."";
$table_name = `test table 1`;
$res = pg_insert ($con , $table_name , $data);
if ($res) {
echo "POST data is successfully logged\n";
} else {
echo "User must have sent wrong inputs\n";

You have two different kinds of databases there. One is MySQL and another is PostgreSQL. Your using a mysql database so use a mysql query to insert.
You need to use mysql query
mysql_query("INSERT INTO $table (column_name, column_name2) VALUES('$value', '$value2')");
Also, you are using mysqli syntax to connect to db. In mysql, the syntax is
$con = mysql_connect ($servername, $username, $password);
mysql_select_db('foo', $con);
And I strongly suggest you to use mysqli. Ancient mysql is no longer supported!
Here's the code in MySQLi
$db = new mysqli("host", "user", "password", "database");
$db->query("INSERT INTO $table (column_name, column_name2) VALUES('$value', '$value2')");
When should I use MySQLi instead of MySQL?
