php - Best Practices for __get() and __set() -

-

__ get () and __ set () on it To use the variable, I want to get input on how they are used in general, I am thinking that when the best time to use the overloading function, and where you have used one (if you have).

Just to be clear, we are talking about these tasks:

Using lazy model gates (__get ())

I do not remember using magic, magic methods are often in my app, but I miss a situation where __ gets () was very helpful.

In those days, I was developing an application in the KP PHP framework which was launched in many models and specific controllers, even though the method was one or two of them (Only the cake was working). So I decided to turn that lazy model into lazy (to load the models used for the first time).

What I did is very simple __ get () function with a specific name that was looking for a model and loaded it 3-4 lines of code Was like. I have defined that in AppController (all the KPPHP classes come out of that controller) and suddenly my app used speed and used less memory.

I took it forward later and loaded the lazy components in the same way.

using dynamic model methods (__call ())

Another good example, from CakePHP, how the model searches for cakes Basically you have two methods for it : find () and findAll () in each model, but you can also use methods like findBy & lt; FieldName & gt; () and findAllBy & lt; FieldName & gt; () .

For example, if you have a DB table 

  notes (id, date, title, body)

Make cake models for You can use the findById () , findByTitle () and similar methods. You only need the Camel CBS DB field and you can search very quickly on any area.

The cake uses the __ call () magic method. This method is called if you are trying to execute a method that does not exist and then It only runs find () or findAll () and the parameter is very simple and you can actually get many benefits.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
