What are the potential risks of directly editing .frm, .myd, and .myi files in PHP MySQL databases?

Directly editing .frm, .myd, and .myi files in PHP MySQL databases can lead to data corruption, loss of data integrity, and potential security vulnerabilities. It is recommended to use SQL queries or database management tools to make changes to the database structure or data. This will ensure proper validation and handling of data, preventing any unintended consequences. 

// Example of using SQL queries to update data in a MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// SQL query to update data in a table
$sql = "UPDATE table_name SET column_name = 'new_value' WHERE condition";

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

// Close connection
$conn->close();
