Hello! I have a multi dimensional array, like this: array('name' => array('title'=>'Title','date'=>'Created')) I store it as JSON 'array', and when I decode it, I want to reach every item by its number, so I want an indexed array. How could I solve this in PHP? Tim ...
I'm trying to merge these 2 arrays $arr1 = array('a' => "1", 'b' => "2", 'c' => "3"); $arr2 = array('a' => "9", 'b' => "8", 'd' => "7"); into an array that looks like this $arr1 = array( 'a' => array("1", "9"), 'b' => array("2", "8"), 'c' => array("3", ""), 'd' => array("", "7") ); The tricky part is the blanks. I...
Hello! I have a multi dimensional array in PHP. $f = array('one' => array(*doesntmatter*), two => array()); When I want to use it, I only want one of the arrays.

Hi all, i have to delete some elements of my array, but without rearrange array. If i use "delete" to delete my elements, the "holes" take up memory? var array=["A","B","C"]; delete array[1]; // array -> ["A", undefined, "C"] I think the deleted element is really deleted so it isn't take up memory space, isn't true? Thanks. ...
Here is a simplified version of what I have (not working): prog.h: ... const string c_strExample1 = "ex1"; const string c_strExample2 = "ex2"; const string c_astrExamples[] = {c_strExample1, c_strExample2}; ... prog.cpp: ... int main() { int nLength = c_astrExamples.length(); for (int i = 0; i < nLength; i++) cout << c_...
I don't think the following should work, but it does: $ perl -e '@a = qw/1222 2 3/; while (<@a>) { print $_ ."\n";}' 1222 2 3 $ As far as I know, Perl's <> operator shoud work on filehandle, globs and so on, with the exception of the literal <> (instead of <FILEHANDLE>), which magically iterates over @ARGV. Does anyone know if it's s...

Hi, I need to store a char array inside a class and then return it. I have to admit that I'm a bit confused about pointers and have tried everything I can think of but can't get it to work. Here's what I have: #include <iostream> using namespace std; class Test { public: void setName(char *name); char getName(); private: c...
I have the following 2 arrays and would like to combine them. I'm more interested in the keys than their values. I'd like to take this $arr1 = array( 'tom' => "1", 'sally' => "20" // unique 'larry' => "2", 'kate' => "3", 'dave' => "23" //unique ); $arr2 = array( 'tom' => "11", 'larry' => "12", 'drummer' => "2",...
I'm trying to resize an array of a certain class passed as an argument, e.g. procedure Resize(MyArray: Array of TObject); begin SetLength(MyArray, 100); end; However, this raises an error "E2008 Incompatible types". Is it true that you can't do this (I've seen rumors, but no official documentation) or am I doing something wrong? ...

Hi! Question's Background: void dash(int *n, char c) is to draw characters c separated by '+'. Parameter n is an array of ints, e.g. {1, 3, 2} and '-' for c should give "+-+---+--+", which works fine. To use dash I do {int f={1, 3, 2}; dash(f, '-');}, which makes the construct copy&pastable. The question itself: To avoid copy&pasting I ...
I have a an array called $ran = array(1,2,3,4); I need to get a random value out of this array and store it in a variable, how can I do this? ...
I spend much of my time programming in R or MATLAB. These languages are typically used for manipulating arrays and matrices, and consequently, they have vectorised operators for addition, equality, etc. For example, in MATLAB, adding two arrays [1.2 3.4 5.6] + [9.87 6.54 3.21] returns an array of the same size ans = 11.07 ...

But when I try to print it with foreach I get an error "Invalid argument supplied for foreach()" foreach($i...
