What potential issues can arise when using the fetchRow function in PHP for database queries?

One potential issue that can arise when using the fetchRow function in PHP for database queries is that it may return false if there are no more rows to fetch. To solve this issue, you can check if the result is false and handle it accordingly, such as by returning an empty array or displaying a message to the user. 

// Fetch a row from the database
$row = $stmt->fetchRow();

// Check if the result is false
if($row === false){
    // Handle the case where no more rows are available
    echo "No more rows to fetch";
} else {
    // Process the fetched row
    // Example: print_r($row);
}
