multidimensional-array

问题 Having a thorny problem and only see similar but also simpler solutions on SO. Is is possible to generate a dynamic key AND dynamic values using JS/JSON? For instance, let's say I have JSON like this: { "email": "user@someco.com", "firstname": "Bob", "lastname": "Smith", "company": "ACME", "custom": { "services": [ { "name": "svc1", "desc": "abcdefg", "selected": "true", "status": "None" }, { "name": "svc2", "desc": "abcdefg", "selected": "true", "status": "None" }, { "name": "svc3", "desc":

问题 Can someone please provide an explanation on the difference of the two PHP arrays below and how they are used with a possible output? $final['a']['b'] = queryX($conn, $id, 'user'); $final['b'] = queryY($conn, $id, 'visitor'); Note that queryX and queryY are functions that contains SQL Queries and returns them as associative arrays. 来源： https://stackoverflow.com/questions/36235787/difference-between-php-arrays-and-possible-output

问题 I have searched around and I am at my wits end so I will make this easy. This is what I have in a print_r: Array ( [0] => Array ( [name] => client interaction [y] => 2.7 ) [1] => Array ( [name] => client interaction [y] => 0.1 ) [2] => Array ( [name] => project planning [y] => 0.1 ) [3] => Array ( [name] => client interaction [y] => 5.9 ) ) And this is what I want it to be: Array ( [0] => Array ( [name] => client interaction [y] => 8.7 ) [1] => Array ( [name] => project planning [y] => 0.1 )

问题 Let's presume I have the following array: Array ( [0] => Array ( [2] => 0 [1] => 0 [0] => 0 ) [1] => Array ( [2] => 1 [1] => 0 [0] => 0 ) [2] => Array ( [2] => 1 [1] => 2 [0] => 0 ) ) How could I order/permute/manipulate this array, to get an array, which contains all possible orderings of each and every sub-array, while maintaining key-value association in sub arrays? I would need a simmilar result like this: Array ( [0] => Array ( [2] => 0 [1] => 0 [0] => 0 ) [1] => Array ( [1] => 0 [2] =>

问题 Please compare the CURRENT and DESIRED results below to see what I'm trying to do. $arr=array( array('list_name'=>'Food', 'list_item'=>'bread'), array('list_name'=>'Food', 'list_item'=>'meat'), array('list_name'=>'Drinks', 'list_item'=>'water'), array('list_name'=>'Drinks', 'list_item'=>'milk') ); foreach($arr as $row){ echo $row['list_name'].'<br>'; echo $row['list_item'].'<br>'; echo '<br>___<br>'; } CURRENT RESULT Food bread ___ Food meat ___ Drinks water ___ Drinks milk ___ DESIRED RESULT

问题 I am new to c, I am using CUDA compiler. I want to declare five matrices, from a[1][1] to a[5][5]. Initialize them with random values. Print these values. I have shown the whole code I wrote. I face problems Passing matrix as parameter Initialize a matrix (should be constant) #include <stdio.h> #include <stdlib.h> void printMatrix(int **a, int rows, int cols) { for(int i=0; i<rows; i++){ for (int j=0; j<cols; j++){ printf("%d\t", a[i][j] ); } printf("\n"); } } int main() { int N; for (int n=0

问题 I am trying to create a matrix table. The values to be plugged into the matrix will be user input from an html table (basically a unique pairing table which pairs two elements at a time and for each pair a user can select which he prefers and by how much it is prefered on a scale of 1-9 using radio buttons). it is the preferences i.e. 1-9 that gets plugged into the matrix table and the number of unique pairing that detemines the lenght of the matrix. when the matric is generated i want to

问题 Need a little help here with summing up arrays inside a multi dimensional php array Eg Multidimensional array Array ( [0] => Array ( [0] => 30 [1] => 5 [2] => 6 [3] => 7 [4] => 8 [5] => 9 [6] => 2 [7] => 5 ) [1] => Array ( [0] => 50 [1] => 4 [2] => 8 [3] => 4 [4] => 4 [5] => 6 [6] => 9 [7] => 2 ) ) I want to have a result array that will be holding sum of both these arrays like this Array ( [0] => 80 [1] => 9 [2] => 14 [3] => 11 [4] => 12 [5] => 15 [6] => 11 [7] => 7 ) Any help will be
