जब मैं अनुपालन कोड चलाऊँगा PHP में 

  यदि ('हाँ' == 0) 'एक' गूंज; Else गूंज 'बी';

आउटपुट एक है।
मुझे क्या हुआ समझ में नहीं आ रहा है? और मैं php कोड को सी स्रोत कोड में परिवर्तित कर सकता हूं कि क्या वास्तविक हो रहा है?

PHP है एक गतिशील रूप से टाइप की गई भाषा, और == एक ढीली तुलना ऑपरेटर है, जिसका अर्थ है कि यह सबसे पहले उसे एक प्रकार, int की तुलना में मूल्य डालेगा बात, और फिर उनकी तुलना; स्ट्रिंग को बायीं भाग से संख्यात्मक ले कर, पूर्णांक में डाली जा रही है, इसलिए 1abc को 1 को डाले जाते हैं। उस तर्क से हाँ को 0 में डालें, और 0 == 0 पैदावार true से।

python - Strange behavior using PyQt4's 'pyqtSlot' decorator before another decorator -

-
I have a strange problem with using the QtCore.pyqtSlot decorator in front of the function decorated with a different decorator. The problem below shows this problem, it immediately provides a low QT program with a single button. When pressing a button, the following happens: (1) The signal 'signal_A' and 'signal_B' sequence are connected to method_A and method_B ​​respectively. (2) signal_A and signal_B signals are emitted. (3) The required behavior is that the method_A and method_B ​​are executed. However, it turns out that both signal_A and signal_B trigger method_A, or method_B ​​(oddly, this is nondeterministic, and different for each part of the program!). It appears to be a bug. This issue is present when PyQt4 binding is used in Qt. It is not present when using PySide (use the '-pyside' parameter to verify) I have seen both problems in Python 2 and 3, and both in Windows and Linux This issue is related to the insertion of a decorator be...

c# - UnhandledExceptionMode.ThrowException for AppDomain.UnhandledException -

-
I want to set unhandledExceptionMode.ThrowException for current AppDomain and not only for application threads. An exception from the second thread should also be handled by my current Donan_Unimated exception handler. Is it possible? Here's my code: Fixed class program {/// & lt; Summary & gt; Main entry point for the application /// & lt; / Summary & gt; [STAThread] static zero major () {applications Set unhandled exception mode (unwanted exception.

Message + environment. Newline); }} Maybe you search for the behavior provided by Applic...

When I try to kill with a command prompt, I get the message: "Access denied" I tried to run as my app administrator and the process was killed. How can I not always use "Run as administrator"?
