  • array_multisort and dynamic variable options.

    - by websiteguru
    Im trying to sort any array with array_multisort and everything is working great. However, based on conditions in my script, I need to change the options. So What I have so far is this: array_multisort( $sort1,SORT_ASC, $sort2,SORT_ASC, $sort3,SORT_ASC, $arraytosort ); and what I would like to have is something like this: $dynamicSort = "$sort1,SORT_ASC,$sort2,SORT_ASC,$sort3,SORT_ASC,"; array_multisort( $dynamicSort, $arraytosort ); Any suggestions?

  • Java interface 'interview'-style problem

    - by Codenotguru
    Problem/Task: Write an interface with one method and two classes that implement this interface. Now write a main method with an array that holds an instance of each class. Using a for-each loop, invoke the method upon each item. Is this an interview question? (I'm not sure if the author meant to post this as a question or was looking for an answer to the above.)

    What I'd like is for this class class Car { public function __construct(Engine $engine, Make $make, Model $model) { // stuff } } Get an array that has the types needed to construct this car (Engine, Make, Model) in the order they are needed for the constructor. I'm using this for a Dependency Injection-esque thing I'm making.

  • typedef and operator overloading in C

    - by jocapco
    Suppose I typedef an integer or integer array or any known type: typedef int int2 Then I overload operator * for int2 pairs, now if I initialize variables a and b as int. Then will my * between a and b be the overloaded * ? How do I achieve overloading an int and yet also use * for int the way they are. Should I create a new type?

  • How to check whether an object has a specific method or not

    - by Ghommey
    Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell whether $myObject has a method called helloWorld or not?

  • Comparing arrays with sql

    - by Nissim
    I want to perform a 'SELECT' statement with a byte array (binary) parameter as a condition. I tried to google it, but didn't find anything useful. In general, I keep information of files in the database. one of the properties is the file's hash (binary). I want to give a hash to the SELECT statement, and get all rows with the same hash value.

  • Take a string to a byte[]

    - by Vaccano
    I have a string in my database that represents an image. It looks like this: 0x89504E470D0A1A0A0000000D49484452000000F00000014008020000000D8A66040.... <truncated for brevity> When I load it in from the database it comes in as a byte[]. How can I convert the string value to a byte array myself. (I am trying to remove the db for some testing code.)

  • ActionScript 3 - access variables in main application class from instantiated class

    - by Herter
    I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information. Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown: "Access of undefined property currentState." Anyone know how this can be solved?

  • Does GCC have a built-in compile time assert?

    - by VladLosev
    Our existing compile-time assert implementation is based on negative array index, and it provides poor diagnostic output on GCC. C++0x's static_assert is a very nice feature, and the diagnostic output it provides is much better. I know GCC has already implemented some C++0x features. Does anyone know if static_assert is among them and if it is then since what GCC version?
