PHP Form Connectivity with Database

This is essential, because the data we get through GET and POST method must be stored somewhere. Ensure you have configured 'php.ini' file before PHP & Database connectivity.  

Create database connection object 

          $conn = new
           

           PDO(  $servername , $username , $password);

 In our example, we connect PHP to a PostgreSQL server by creating a $conn connectivity object with three parameters: server host name or IP address and database name, database username, and database password 

SQL statement and its execution 

Note: $sql = "INSERT INTO student  

(name, gender) VALUES  

(.$name., .$gender.)"; 

The above statement creates SQL string to insert values in the table named student.  $conn -> exec($sql);  

In the above statement ‘->’ is used to execute SQL statement using $conn as connectivity object.
