I am stuck with PHP's array()? -

-

Why did the array () function pass in? I'm unable to understand the array () function. I know that $ _POST does not have any value, it passes under the array () , but what is the value in array () ? 

  some functions ($ _ POST? $ _POST: array ());

array () is not a function copy, it A language is formed. But simply by using the array () you can prepare an empty array for you, which is with zero elements.

You might want to check for: 

  issued ($ _ POST)? $ _POST: Array ()

Edit:

As told by Greg, $ _ POST will always be set. So there is no need to check it and return an empty array. someFunc ($ _ POST) must do the same thing.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks.

delphi - Mouseover hint for TChart series value -

Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
