Here is the code:
$arraya = array('a','b','c');
foreach($arraya as $key=>$value)
{
if($value == 'b')
{
$arraya[] = 'd';
//print_r($arraya); //$arraya now becomes array('a','b','c','d')
}
echo $key.' is '.$value."\n";
}
and it will get:
0 is a
1 is b
2 is c
And I wonder why 3 is d doesn't show up??
Hello,
I have a field in my DB that holds value separated by commas like;
$tmp_list = "COB,ISJ,NSJ,"
Now when I fetch that the row, I would like to have them in an array.
I have used array($tmp_list) but I get the values in one line only like:
[0] => 'COB,ISJ,NSJ,'
instead of
[0] => 'COB',
[1] => 'ISJ',
[2] => 'NSJ'
All help is appriciated.
The CakePHP Cookbook states that a Model can use a file (csv for example) instead of an actual database table but I couldn't find any implementation for it.
I was wondering if it is possible to use an Array of data as a model in CakePHP since I have a fairly static set of data which is important to me in a relationship with another table but it doesn't make a whole lot of sense to create a complete table for it.
Is it possible to implement a CakePHP Model using an Array?
I have a simple one level deep vocabulary taxonomy. Something like Vocabulary-Term-Node. What I want to know is if there's a built in function to get an array of nodes related to a single term, something like taxonomy_select_nodes() but that would return an array of nodes instead of a string.
Is there significant cpu/memory overhead associated with using automatic arrays with g++/Intel on 64-bit x86 linux platform?
int function(int N) {
double array[N];
overhead compared to allocating array before hand (assuming function is called multiple times)
overhead compared to using new
overhead compared to using malloc
The range of N may be from 1kb to 16kb roughly, stack overrun is not a problem.
Hi chaps, I have an array of nsdictionaries and one key is ID (which is unique) I simply want to see if the the array of dictionaries contains a specific ID.
Really simple but its friday and after statiny up watching the election i think my brain is melting. Any help would be great.
Thanks
All,
I have an array with hyphens in the key name. How do I extract the value of it in PHP? It returns a 0 to me, if I access like this:
print $testarray->test-key;
This is how the array looks like
testarray[] = {["test-key"]=2,["hotlink"]=1}
Thanks
I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do
a[0,:]
However, in case a happens to be a 1xn vector, this code above returns an index error:
IndexError: too many indices
As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?
Hello,
I have some difficulties for using Ruby block, passing in a method.
As in the following case, I would like to display each element of @array, from Box instance (using .each method):
class Box
def initialize
@array = [:foo, :bar]
end
def each(&block)
# well, hm..
end
end
a = Box.new
a.each { |element| puts element }
Thanks for any help.
for example i have array
int a[]=new int[]{3,4,6,2,1};
I need list of all permutation such that if one is like this, {3,2,1,4,6}, others must not be the same i know that if length of array=n then there is n! possible combination please help me to write this algortihm what to do?
I read at many tutorials that the current best practices to create a new javascript array is to use "var arr = []" instead of "var arr = new Array()".
What's the reasoning behind that?
Hi,
I want to have an array of struct (an array of books with their specifications like publication, ISBN number, ...). in wsdl and php. I have searched a little and I have found files that uses Nusoap, However, I dont want to use NuSoap. Is there any solution? I would appreciate if you help me in writing the related wsdl, client and server (php) files.
Thank you so much.
Best, shadi.
I got asked this question once and still haven't been able to figure it out:
You have an array of N integers, where N is large, say, a billion. You want to calculate the median value of this array. Assume you have m+1 machines (m workers, one master) to distribute the job to. How would you go about doing this?
Since the median is a nonlinear operator, you can't just find the median in each machine and then take the median of those values.
somehow couldn't find this with a google search, but I feel like it has to be simple...I need to convert a string to a fixed-length byte array, e.g. write "asdf" to a byte[20] array. the data is being sent over the network to a c++ app that expects a fixed-length field, and it works fine if I use a BinaryWriter and write the characters one by one, and pad it by writing '\0' an appropriate number of times.
is there a more appropriate way to do this?
For example, input is
Array 1 = [2, 3, 4, 5]
Array 2 = [3, 2, 5, 4]
Minimum number of swaps needed are 2.
The swaps need not be with adjacent cells, any two elements can be swapped.
I am looking for a way to easily split a python array in half.
So that if I have an array:
A = [0,1,2,3,4,5]
I would be able to get:
B = [0,1,2]
C = [3,4,5]
I'm trying to declare an enum type based on data that I'm retrieving from a database. I have a method that returns a string array of all the rows in the table that I want to make into an enumerated type. Is there any way to construct an enum with an array?
This is what I tried, but from the way it looked in eclipse, it seemed like this just created a method by that name:
public enum ConditionCodes{
Condition.getDescriptions();
}
Thank you in advance!
Let us say that we have following array:
my @arr=('Jan','Feb','Mar','Apr');
my @arr2=@arr[0..2];
How can we do the same thing if we have array reference like below:
my $arr_ref=['Jan','Feb','Mar','Apr'];
my $arr_ref2; # How can we do something similar to @arr[0..2]; using $arr_ref ?
Im using the answer to this question to convert an array of XML to a single XML output:
http://stackoverflow.com/questions/2554671/output-array-of-xml-to-plain-xml
Im using the simpler solution of the two there (Marked as the answer)
It all works for me, however at the start of the output I get:
string(109960) "
Can anyone shed any light on this? Output here: http://bit.ly/aoA3qY
Is there a way to initialize an array of primitives, say a integer array, to 0? Without using a for loop? Looking for concise code that doesn't involve a for loop.

Hi,
I have an array of type string that looks like this:
"test1|True,test2|False,test3|False,test4|True".
This is essentially a 2d array like so
[test1][True]
[test2][False]
[test3][False]
[test4][True].
I want to convert this into a dictionary<string,bool> using linq, something like:
Dictionary<string, bool> myResults = results.Split(",".ToCharArray).ToDictionary()
any ideas?
Hi all,
I came cross a question in my interview.
Question:
Array of integers will be given as the input and you should find out the middle element when sorted , but without sorting.
For Example.
Input: 1,3,5,4,2
Output: 3
When you sort the given input array, it will be 1,2,3,4,5 where middle element is 3.
You should find this in one pass without sorting.
Any solutions for this?
