Are there any best practices for handling Oracle database connections in PHP?

When working with Oracle databases in PHP, it is important to properly handle database connections to ensure efficiency and security. One best practice is to establish a connection to the Oracle database using the OCI8 extension and close the connection when it is no longer needed. Additionally, using prepared statements for querying the database can help prevent SQL injection attacks. 

// Establishing a connection to the Oracle database
$conn = oci_connect('username', 'password', 'localhost/XE');

if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

// Querying the database using prepared statements
$query = oci_parse($conn, 'SELECT * FROM table_name WHERE column = :value');
$value = 'example';
oci_bind_by_name($query, ':value', $value);
oci_execute($query);

// Closing the database connection
oci_close($conn);
