php - How to know when an array pointer has reached the end where's there are no items -


I'm using end () to get the last array object, but I do not want it

I want to know that when there are no items and starts with the beginning of the array.

$ current = $ _SESSION ['current_sang']; $ Song_are = explosion (',', $ _SESSION ['song_aray']); $ Nextkey = array_search ($ current, $ song_array) + 1; $ Last_song = end ($ song_array); If ($ next key == calculation ($ song_array)) {$ nextkey == 0; } $ Next = $ song_array [$ nextkey]; If ($ next == $ last_song) {$ sid = $ song_array [0]; } And {$ sid = $ next; ($ Element = current ($ song_array)) {/ code> 

  For, as long as we do not reach the end of Sir / // print_r ($ element) and see what you have ... // When finished, go to the next element next ($ song_array); } // Reset pointer in the beginning, if you like reset ($ song_array);

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
