How can PHP handle database entries with NULL values?

When handling database entries with NULL values in PHP, it's important to check for NULL values before using them in your code to avoid potential errors. One way to handle NULL values is to use conditional statements to check if the value is NULL before performing any operations on it. This ensures that your code can handle NULL values gracefully without causing any issues. 

// Assuming $row is an array containing database entries
if ($row['column_name'] !== NULL) {
    // Perform operations on the value if it is not NULL
    echo $row['column_name'];
} else {
    // Handle NULL value appropriately
    echo "Value is NULL";
}
