Prepared statements encrypt the SQL query and the data, making it unreadable to attackers even if intercepte

Prepared statements separate the SQL query structure from the data, preventing SQL injection by treating data as literal values, not executable code.

Bind parameters to the prepared statement object, then execute the statement.

Execute the statement, then retrieve the statement object again to bind parameters.
