What are the consequences of reusing a database result set in PHP without resetting the cursor?

When reusing a database result set in PHP without resetting the cursor, it can lead to unexpected behavior such as missing or duplicate data being fetched. To solve this issue, you should reset the cursor of the result set back to the beginning before reusing it. 

// Assuming $result is the database result set

// Reset the cursor of the result set back to the beginning
mysqli_data_seek($result, 0);

// Now you can reuse the result set without any issues
// Example: iterate over the result set again
while ($row = mysqli_fetch_assoc($result)) {
    // Process each row
}
