How can a string variable be converted to a mysqli type variable in PHP?

To convert a string variable to a mysqli type variable in PHP, you can use the mysqli_real_escape_string() function. This function escapes special characters in a string for use in an SQL statement, making it safe to use in queries. By using this function, you can prevent SQL injection attacks and ensure that your queries are secure. 

// Assuming $stringVariable contains the string you want to convert
$mysqli = new mysqli("localhost", "username", "password", "database");

// Convert string variable to mysqli type variable
$escapedString = $mysqli->real_escape_string($stringVariable);

// Now $escapedString can be safely used in SQL queries
