What potential issues could arise from storing dates as integers instead of using the appropriate date format in a database?

Storing dates as integers instead of using the appropriate date format in a database can lead to difficulties in querying and manipulating the data. It can also result in errors when converting the integers back to dates for display purposes. To solve this issue, it is recommended to store dates in the database using the appropriate date format (e.g., YYYY-MM-DD).

// Storing dates in the database using the appropriate date format
$date = "2022-01-15";
$query = "INSERT INTO table_name (date_column) VALUES ('$date')";
$result = mysqli_query($connection, $query);
