What potential issues can arise when storing date strings in a VARCHAR field in PHP?

Storing date strings in a VARCHAR field in PHP can lead to potential issues such as difficulty sorting or comparing dates accurately. To solve this problem, it is recommended to store dates in a DATE or DATETIME field in the database, as this allows for easier manipulation and comparison of dates. 

// Example of storing date in a DATE field in MySQL database

$result = mysqli_query($connection, $query);
