What does the error "Column count doesn't match value count at row 1" in MySQL mean in PHP?

The error "Column count doesn't match value count at row 1" in MySQL means that the number of columns being inserted into does not match the number of values being provided in the query. This can happen when there are missing or extra columns in the INSERT statement. To solve this issue, ensure that the number of columns being inserted into matches the number of values being provided.

// Example of correct INSERT statement
$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);
}
