Use the following code to connect and create a table by using **CREATE TABLE** SQL statement.

The code uses the **MySQL Improved extension** (mysqli) class included in PHP. The code calls methods [mysqli_init](https://www.php.net/manual/en/mysqli.init.php) and [mysqli_real_connect](https://www.php.net/manual/en/mysqli.real-connect.php) to connect to MySQL. Then it calls method [mysqli_query](https://www.php.net/manual/en/mysqli.query.php) to run the query. Then it calls method [mysqli_close](https://www.php.net/manual/en/mysqli.close.php) to close the connection.
In addition to the procedural style, you can also connect to Azure Database for MySQL using the object-oriented interface provided by the mysqli extension in PHP.

Replace the host, username, password, and db_name parameters with your own values.

## Insert data

Use the following code to connect and insert data by using an **INSERT** SQL statement.

The code uses the **MySQL Improved extension** (mysqli) class included in PHP. The code uses method [mysqli_prepare](https://www.php.net/manual/en/mysqli.prepare.php) to create a prepared insert statement, then binds the parameters for each inserted column value using method [mysqli_stmt_bind_param](https://www.php.net/manual/en/mysqli-stmt.bind-param.php). The code runs the statement by using method [mysqli_stmt_execute](https://www.php.net/manual/en/mysqli-stmt.execute.php) and afterwards closes the statement by using method [mysqli_stmt_close](https://www.php.net/manual/en/mysqli-stmt.close.php).
In addition to the procedural style, you can also connect to Azure Database for MySQL using the object-oriented interface provided by the mysqli extension in PHP.

## Read data

Use the following code to connect and read the data by using a **SELECT** SQL statement. The code uses the **MySQL Improved extension** (mysqli) class included in PHP. The code uses method [mysqli_query](https://www.php.net/manual/en/mysqli.query.php) perform the sql query and method [mysqli_fetch_assoc](https://www.php.net/manual/en/mysqli-result.fetch-assoc.php) to fetch the resulting rows.
In addition to the procedural style, you can also connect to Azure Database for MySQL using the object-oriented interface provided by the mysqli extension in PHP.

## Update data

Use the following code to connect and update the data by using an **UPDATE** SQL statement.

The code uses the **MySQL Improved extension** (mysqli) class included in PHP. The code uses method [mysqli_prepare](https://www.php.net/manual/en/mysqli.prepare.php) to create a prepared update statement, then binds the parameters for each updated column value using method [mysqli_stmt_bind_param](https://www.php.net/manual/en/mysqli-stmt.bind-param.php). The code runs the statement by using method [mysqli_stmt_execute](https://www.php.net/manual/en/mysqli-stmt.execute.php) and afterwards closes the statement by using method [mysqli_stmt_close](https://www.php.net/manual/en/mysqli-stmt.close.php).

## Delete data

Use the following code to connect and read the data by using a **DELETE** SQL statement.

The code uses the **MySQL Improved extension** (mysqli) class included in PHP. The code uses method [mysqli_prepare](https://www.php.net/manual/en/mysqli.prepare.php) to create a prepared delete statement, then binds the parameters for the where clause in the statement using method [mysqli_stmt_bind_param](https://www.php.net/manual/en/mysqli-stmt.bind-param.php). The code runs the statement by using method [mysqli_stmt_execute](https://www.php.net/manual/en/mysqli-stmt.execute.php) and afterwards closes the statement by using method [mysqli_stmt_close](https://www.php.net/manual/en/mysqli-stmt.close.php).
