What potential issues can arise when using PHP to display values from a MySQL table for specific years?

One potential issue that can arise when using PHP to display values from a MySQL table for specific years is that the year value may need to be properly formatted to match the format stored in the database. This can lead to discrepancies in the data being retrieved. To solve this issue, you can use the DATE_FORMAT function in your SQL query to format the year value before retrieving it in PHP.

// Assuming $year is the specific year you want to retrieve data for
$query = "SELECT * FROM table_name WHERE DATE_FORMAT(date_column, '%Y') = $year";
$result = mysqli_query($connection, $query);

if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Display the data
    }
} else {
    echo "No results found for the year $year.";
}
