php - deleting all files from a folder, excluding some files from being deleted -

-

The following thread (first post) I have successfully completed the deletion of all files from the folder using php.

This is the code I use: 

  $ files = glob ('path / to / temp / *'); // get all file name foreach ($ files as $ files) {// iterative files if (is_file ($ file)) unlink ($ file); // delete file}

I want to exclude some files from being deleted. What code adjustment should I apply? 

  $ files = glob ('path / per / temporary / *'); // Receive all filename $ exemption = [["amazingfile_a", "amazingfile_b"]; Foreign Currency (files as $ $ file) {// ifre file (if_file ($ file) and amp; amp;; in_array (end (explosion ("/", $ file)), $ exceptions ($ File); // delete file}

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
