arrays - PHP syntax for dereferencing function result -

पृष्ठभूमि

हर दूसरे प्रोग्रामिंग भाषा में मैं नियमित आधार पर उपयोग करता हूं , फ़ंक्शन के परिणाम को पकड़ने के लिए एक नया चर घोषित किए बिना किसी फ़ंक्शन के रिटर्न मान पर काम करना सरल होता है।

PHP में, हालांकि, यह इतना आसान नहीं दिखता है:

< H3> example1 (फ़ंक्शन का परिणाम एक सरणी है) 
  & lt;? Php फ़ंक्शन फ़ूबार () {वापस preg_split ('/ \ s + /', 'शून्य एक दो तीन चार पांच'); } // क्या php "शून्य" कह सकता है? /// प्रिंट (फोबोर () [0]); /// & lt; - नहीं /// प्रिंट (& amp; foobar () [0]); /// & lt; - नहीं /// प्रिंट (& amp; foobar () - & gt; [0]); /// & lt; - नहीं /// प्रिंट ("$ {foobar ()} [0]"); /// & lt; - नहीं? & Gt;

example2 (फ़ंक्शन परिणाम एक ऑब्जेक्ट है) 

  & lt;? Php फ़ंक्शन zoobar () {// नोट: कास्टिंग (वस्तु) सरणी () है PHP में अन्य समस्याएं / देखें, जैसे http://stackoverflow.com/questions/1869812 $ vout = (वस्तु) सरणी ('0' = & gt; 'शून्य', 'fname' = & gt; 'होमर', 'lname '= & gt;' सिम्पसन ',); वापसी $ vout; } // क्या php "शून्य" कह सकता है? // प्रिंट ज़ोओबार () - & gt; 0; // & lt; - नहीं (पार्स त्रुटि) // प्रिंट ज़ोबर () - & gt; {0}; // & lt; - nope // print zoobar () - & gt; {'0'}; // & lt; - नहीं / $ vtemp = zoobar (); // एक चर मदद का उपयोग करता है? // प्रिंट $ vtemp- & gt; {0}; // & lt; - notope

क्या कोई यह सुझाव दे सकता है कि यह कैसे PHP में है?

यह विशेष रूप से सरणी परिभाषित है, जो वर्तमान में php5.3 में असमर्थित है लेकिन अगले रिलीज में संभव होना चाहिए, 5.4। ऑब्जेक्ट डिफेंफरिंग चालू पीएचपी रिलीज में संभवतः दूसरी तरफ है। मैं भी इस कार्यक्षमता के लिए उत्सुक हूं!

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...
