What best practices should be followed to prevent the error "Column count doesn't match value count at row 1" when working with MySQL queries in PHP?

The error "Column count doesn't match value count at row 1" occurs when the number of columns specified in an INSERT query does not match the number of values being inserted. To prevent this error, always ensure that the number of columns and values match in your INSERT query. 

// Example of preventing "Column count doesn't match value count at row 1" error
// Ensure that the number of columns and values match in your INSERT query

// Correct way to insert data into a table with 3 columns
$sql = "INSERT INTO table_name (column1, column2, column3) VALUES ('value1', 'value2', 'value3')";
$result = mysqli_query($connection, $sql);

if ($result) {
    echo "Data inserted successfully.";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($connection);
}
