To execute a query in a MySQL database using PHP, you can use the mysqli_query() function. This function takes two parameters: the MySQLi object representing the database connection and the SQL query to be executed. It returns a result object that can be used to fetch data or perform other operations. It is important to use prepared statements or proper escaping techniques to prevent SQL injection vulnerabilities when executing user-supplied data as part of the query.
