The error message "unable to jump to row 0" in PHP MySQL result index 7 signifies that the result set is empty or the cursor is at an invalid position.

if(mysqli_num_rows($result) > 0) {
    // Fetch and process the rows
    while($row = mysqli_fetch_assoc($result)) {
        // Process each row
    }
} else {
    // Handle case when result set is empty
}
