How can the error handling in the PHP code be improved to identify issues with the query?

The error handling in the PHP code can be improved by using the `mysqli_error()` function to capture any errors that occur during the execution of the query. This function will return a string description of the last error that occurred, allowing us to identify and troubleshoot any issues with the query. 

// Execute the query
$result = mysqli_query($conn, $sql);

// Check for errors
if (!$result) {
    echo "Error: " . mysqli_error($conn);
} else {
    // Process the query result
}
