  • Understanding an interesting array update/replace function

    - by dave
    I'm a PHP amateur. This array function is an adaption of a function I noticed while reading this article. I thought this was an interesting type of array function, but I have a question about the way it works. my_func( array( 'sky' => 'blue' ) ); function my_func( array $settings = array() ) { $settings = $settings + array( 'grass'=>'green','sky'=>'dark' ); print_r( $settings ) ; // outputs: Array ( [sky] => blue [grass] => green ) } but..................... my_func( array( 'sky' => 'blue' ) ); function my_func( array $settings = array() ) { $settings = array( 'clock'=>'time' ) ; $settings = $settings + array( 'grass'=>'green','sky'=>'dark' ); print_r( $settings ) ; // outputs: Array ( [clock] => time [grass] => green [sky] => dark ) } Why does [sky] not equal 'blue' in the second instance? Thanks.

  • Bioperl, equivalent of IO::ScalarArray for array of Seq objects?

    - by Ryan Thompson
    In perl, we have IO::ScalarArray for treating the elements of an array like the lines of a file. In BioPerl, we have Bio::SeqIO, which can produce a filehandle that reads and writes Bio::Seq objects instead of strings representing lines of text. I would like to do a combination of the two: I would like to obtain a handle that reads successive Bio::Seq objects from an array of such objects. Is there any way to do this? Would it be trivial for me to implement a module that does this? My reason for wanting this is that I would like to be able to write a subroutine that accepts either a Bio::SeqIO handle or an array of Bio::Seq objects, and I'd like to avoid writing separate loops based on what kind of input I get. Perhaps the following would be better than writing my own IO module? sub process_sequences { my $input = $_[0]; # read either from array of Bio::Seq or from Bio::SeqIO my $nextseq; if (ref $input eq 'ARRAY') { my $pos = 0 $nextseq = sub { return $input->[$pos++] if $pos < @$input}; } } else { $nextseq = sub { $input->getline(); } } while (my $seq = $nextseq->()) { do_cool_stuff_with($seq) } }

  • How to mark array value types in PHP (Java)Doc?

    - by Christian Sciberras
    It might be a bit difficult to explain, so I'll give some example code. Note that I'm using NetBeans IDE (latest). class Dummy { public function say(){ } } /** * Builds dummy class and returns it. * @return Dummy The dummy class. */ function say_something(){ return new Dummy(); } $s=say_something(); While developing in netbeans I can invoke auto-complete by hitting ctrl+space after typing "$s-". In the the hint window that follows, there is the item "say()". This is because the javadoc says say_something returns a Dummy and NetBeans parsed Dummy class to know that it has a method called "say()". So far so good. My problem is with arrays. Example code follows: /** * Builds array of 2 dummy classes and returns it. * @return Array The dummy class. (*) */ function say_something2(){ return array(new Dummy(),new Dummy()); } $s=say_something2(); If I try the auto-complete thing again but with "$s[0]-" instead, I don't get the methods fro Dummy class. This is because in the JavaDoc I only said that it is an array, but not the values' type. So the question would be, is there any JavaDoc syntax, cheat, whatever which allows me to tell JavaDoc what type of variables to expect in an array?

  • How can I find the last value in a multidimensional array in php?

    - by Chris
    I am using a multidimensional array and I am trying to use php to find the last value of one of the arrays and based on that last number(value), add one more to it. Here is my multidimensional array structure: $_SESSION['cart']['add_complete'][1]['deck_id'] I am trying to create this structure, but instead of where it says 1 now, I want to find out what the last number in the add_complete array is and then add one more to it and put that in the place of the 1. How can I do that?

  • How do I shift items in an array in C#?

    - by Andy Evans
    Let's say that I have an array of strings like this: 1, 2, 3, 4, 5, 6, 7, 8 and I want to shift the elements of the array such that The first element always remains fixed Only the remaining elements get shifted like so ... The last element in the array becomes the 2nd element and is shifted through the array with each pass. Pass #1: 1, 2, 3, 4, 5, 6, 7, 8 Pass #2: 1, 8, 2, 3, 4, 5, 6, 7 Pass #3: 1, 7, 8, 2, 3, 4, 5, 6 Pass #4: 1, 6, 7, 8, 2, 3, 4, 5 Any assistance would be greatly appreciated.

  • Numpy: Creating a complex array from 2 real ones?

    - by Duncan Tait
    I swear this should be so easy... Why is it not? :( In fact, I want to combine 2 parts of the same array to make a complex array: Data[:,:,:,0] , Data[:,:,:,1] These don't work: x = np.complex(Data[:,:,:,0], Data[:,:,:,1]) x = complex(Data[:,:,:,0], Data[:,:,:,1]) Am I missing something? Does numpy not like performing array functions on complex numbers? Here's the error: TypeError: only length-1 arrays can be converted to Python scalars Cheers

  • Filtering a PHP array containing dates into a yearly summary

    - by privateace
    I'm looking at a way to create a summary of transactions within a certain month based on the contents of a PHP array. Intended outcome (excusing layout): ------------------------------------------- | December 2009 | 12 | | January 2010 | 02 | | February 2010 | 47 | | March 2010 | 108 | | April 2010 | 499 | ------------------------------------------- Based on my array: Array ( [0] => Array ( [name] => 2009-10-23 [values] => Array ( [0] => INzY2MTI4ZWM4OGRm ) ) [1] => Array ( [name] => 2009-10-26 [values] => Array ( [0] => IYmIzOWNmMmU3OWQz ) ) [2] => Array ( [name] => 2009-11-23 [values] => Array ( [0] => INTg4YzgxYWU1ODkx [1] => IMjhkNDZkY2FjNDhl ) ) [3] => Array ( [name] => 2009-11-24 [values] => Array ( [0] => INTg4YzgxYWU1ODkx [1] => INTg4YzgxYWU1ODkx ) ) [4] => Array ( [name] => 2009-12-01 [values] => Array ( [0] => IMWFiODk5ZjU1OTFk ) ) I've had absolutely no luck no matter what I've tried. Especially with adding months that do not contain any variables.

  • How to fill two-dimensional array using java enhanced loop?

    - by Shark
    Basically, I am trying this, but this only leaves array filled with zeros. I know how to fill it with normal for loop (such as for (int i = 0; i < array.length; i++) and so on), but why is my variant is not working? Any help would be appreciated. char[][] array = new char[x][y]; for (char[] row : array) for (char element : row) element = '~';

  • Accessing appropriate array of double arrays in order of last created.

    - by Zach
    I have an array of double arrays, they are within a specified time window (8am-5pm), and are in order of last created over a period of several days. They are all timestamped and as such I have access to all C# DateTime methods. I then have a different iterative function that goes in the same order of the array of double arrays, however it isn't within a specified time window, it's 24/7. I want to access from this iterative function, the appropriate double array from the one within the window. Let's say that it's 4:30PM on DayOfYear 52, I'd like to access the last double array less than or equal to 4:30PM on DayOfYear 52. I'd expect the same double array if the time were 12:30AM on DayOfYear 53. However, if it were 9:00 AM of DayOfYear 53, well then I'd expect it to return something from the DayOfYear 53, less than or equal to 9:00AM. I think you get the idea. So I'm a having a bit of trouble grokking how to do this. Is anyone willing to offer a starting point or how they'd approach it? Edit: It is not a literal double[][], it is exactly as Anthony Pegram says: Dictionary<DateTime, double[]>

  • Is it good practice to initialize array in C/C++?

    - by sand
    I recently encountered a case where I need to compare two files (golden and expected) for verification of test results and even though the data written to both the files were same, the files does not match. On further investigation, I found that there is a structure which contains some integers and a char array of 64 bytes, and not all the bytes of char array were getting used in most of the cases and unused fields from the array contain random data and that was causing the mismatch. This brought me ask the question whether it is good practice to initialize the array in C/C++ as well, as it is done in Java?

  • How to make sure a method returns an array, even when there is only one element in Ruby

    - by doctororange
    I have a Ruby method that searches an array of hashes and returns a subset of that array. def last_actions(type = 'all') actions = @actions if type == 'run' actions = actions.select {|a| a['type'] == "run" } end return actions end This works, except when there is only one action to return, in which case I don't think it is returning an array with one element, but just the element itself. This becomes problematic later. What's a good way to ensure it returns an array of 1 element in this case? Thanks.

  • PHP: Collect all variables passed to a function as array?

    - by Industrial
    Hi everybody, I was thinking about the possibility of accessing all the variables that are passed into an function, and merge them into an array. (Without passing variables into an array from the beginning) Pseudo-code: // Call function newFunction('one', 'two', 'three' ) ;// All values are interpreted as a one rray in some way // Function layout newFunction( ) { // $functionvariables = array( All passed variables) foreach ($functionvariable as $k => $v) { // Do stuff } }

  • Sorting/grouping when there are multiple values in one cell

    - by ngm
    I have an Excel 2007 spreadsheet, where each row of the dataset describes a feature of a piece of software. One of the columns in the spreadsheet is Relevant Users, which describes which users of the software the feature is of interest to. There may be a couple of different users interested in a feature, in which case I've been filling in the cell with the two user types separated by a colon, e.g. 'Usertype A; Usertype D'. Occassionally, I'd like to sort my data by the Relevant Users column. However, the way I'm populating the column means the sorting isn't very smart. If I have a feature where 'Relevant Users' is 'Usertype A; Usertype D', and then I sort by Relevant Users, that feature will be grouped at the end of all the other features of relevant to Usertype A, as it's just sorting alphabetically. But I want it to be listed in the two separate groups of Usertype A and Usertype D. Or, if I have a pivot table that groups the features together under the heading of Relevant User, I'll get all the features for 'Usertype A', then 'Usertype B', then 'Usertype C', then 'Usertype D', then 'Usertype A; Usertype D', etc. Whereas I really want a feature with Relevant Users as 'Usertype A; Usertype D' to show up in both the Usertype A group and the Usertype D group. I guess if this information was in a database I might have a many-to-many table linking Relevant Users to features. But is there a way to go about having this kind of many-to-many relationship in Excel?

  • SQLAlchemy custom sorting algorithms when using SQL indexes

    - by David M
    Is it possible to write custom collation functions with indexes in SQLAlchemy? SQLite for example allows specifying the sorting function at a C level as sqlite3_create_collation(). An implementation of some of the Unicode collation algorithm has been provided by James Tauber here, which for example sorts all the "a"'s close together whether they have accents on them or not. Other examples of why this might be useful is for different alphabet orders (languages other than English) and sorting numeric values (sorting 10 after 9 rather than codepoint order.) Is this possible in SQLAlchemy? If not, is it supported by the pysqlite3 or MySQLdb modules, or for any other SQL database modules supported by python for that matter? Any information would be greatly appreciated.

  • jQuery: Sorting hierarchical data?

    - by Industrial
    Hi everybody, I have tried for some time to work out a way of sorting nested categories with jQuery. I failed to build my own plugin to do this, so I tried to find something that were available already. Tried a few hours now with this one, http://www.jordivila.net/code/js/jquery/ui-widgetTreeList_inheritance/widgetTreeListSample.aspx and cant get it to work. What are the alternatives of creating a jQuery / jQuery UI script that handles sorting children and parent categories in a way that can be combined with a AJAX PHP backend to handle the actual sorting in the database? Thanks!

  • PHP sorting issue with simpleXML

You can see that in the array I can make it sort by the attribute 'statename'. What I am having trouble with is echoing out and combining the two functions in order to have it auto sort both the states and the cities within and forming the needed optgroups. I tried copying the lines for the cities and changing the names called several ways to no avail.

  • HP MSA 1000 SAN: Can I use 1 array/shelf?

    - by CC
    Hi all, I'm planning some expansion on an HP MSA1000 SAN. My boss says that we need to have two separate arrays on the new enclosure, one for Bays 1-7, the other for Bays 8-14. Is there any reason that we need to do this? My plan was to have the entire expansion shelf be 1 array, then create RAID 6 logical drives from that. I don't understand what splitting drives into separate arrays gain us. We don't have dual controllers, so there's no benefit there. Thanks, CC
