The given code defines a class called DatabaseConnection
. It has private properties $dbConnection
and $bConnected
which are initially set to null
and false
respectively.
The class has a constructor method that initializes the database connection using the values set in the $_ENV
superglobal array. It creates a MySQL connection using the mysqli_init()
function and sets the SSL parameters. Then, it tries to establish a connection using the real_connect()
method of the mysqli
object. If the connection fails, it outputs an error message and terminates the script. If the connection is successful, it can optionally output a success message.
The class also has a getConnection()
method that returns the database connection object and a closeConnection()
method that closes the database connection and sets the $bConnected
property to false
.
Additionally, there is an executeQuery($query)
method that executes a given SQL query on the database using the query()
method of the database connection object. The result of the query is returned.
Overall, this class provides a way to establish a database connection, execute SQL queries, and close the connection.
