In the context of the provided PHP code, what are some common reasons why data is not being correctly inserted into the database despite no apparent errors being reported?

One common reason why data may not be correctly inserted into the database despite no errors being reported is due to incorrect data types or formatting mismatches between the PHP variables and the database columns. Ensure that the data being passed to the database matches the expected data types and formats. Additionally, check for any constraints or triggers in the database that may be preventing the insertion of data. 

// Ensure correct data types and formats are being used before inserting into the database
$name = mysqli_real_escape_string($conn, $_POST['name']);
$email = mysqli_real_escape_string($conn, $_POST['email']);
$age = (int)$_POST['age']; // Ensure age is converted to integer if necessary

// Insert data into the database
$sql = "INSERT INTO users (name, email, age) VALUES ('$name', '$email', $age)";
if (mysqli_query($conn, $sql)) {
    echo "Data inserted successfully";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
