  • Can PHP and Oracle pass complex types to each other?

    - by RenderIn
    I want to pass/bind an array of (key1, key2) to an Oracle PL/SQL stored procedure using PHP. I'm able to bind primitive types and arrays of primitive types, but haven't found a way to pass complex datatypes back and forth. Is this unsupported? So far I've been having to pass along multiple arrays -- one for each subtype in my complex type -- and then depend on their indexes to reconstitute them in the procedure.

  • 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.

  • How can I get a list of the most recent tags in a wordpress database?

    - by Failpunk
    I am not familiar with the wordpress schema at all and I need to get back a list, or array of the most recent tags from any post in the wordpress database. I just need the data available on the home page so I can then manipulate it. All the functions seem to be designed to work on a per-post basis. (Wordpress really makes me feel sorry for frequent wordpress programmers.)

  • 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?

  • 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?
