What are the potential pitfalls of storing dates as strings in a table in PHP?

Storing dates as strings in a table in PHP can lead to issues with sorting, filtering, and performing date-related calculations. It is recommended to store dates in a proper date format (such as MySQL's DATE or DATETIME format) to ensure data integrity and enable efficient date manipulation. 

// Example of storing dates in a proper DATE format in a MySQL table
// Assuming $conn is a valid MySQL connection object

$date = "2022-01-15"; // Date in YYYY-MM-DD format

$query = "INSERT INTO table_name (date_column) VALUES ('$date')";
$result = mysqli_query($conn, $query);

if($result) {
    echo "Date stored successfully.";
} else {
    echo "Error storing date: " . mysqli_error($conn);
}
