Suppose if your $request->option contain array then $filtered = collect($request->option)->whereNotNull(‘option’)->all()->toArray(); Ref: https://laravel.com/docs/8.x/collections#method-wherenotnull solved How do I loop a nested array in laravel to get an array based on conditions of key values from that array
To be honest I didn’t fully understand your code sample, but in the following IF-block: if(b>1 || l<Laenge) b can still be 0 because it’s an OR statement, so later inside this IF-block the statements new_Ver[n]=new_Ver_s[l,b-1]; new_UV[n]=new_UV_s[l,b-1]; will try to index at -1. 2 solved Array index is out of range but the index is … Read more
not really sure the purpose of this exercise but this gets your desired result with the given data $objects = [ (object) [‘id’=> 1, ‘value’ => 0], (object) [‘id’=> 2, ‘value’ => 10], (object) [‘id’=> 3, ‘value’ => 14], (object) [‘id’=> 4, ‘value’ => 0], (object) [‘id’=> 5, ‘value’ => 21], (object) [‘id’=> 6, ‘value’ … Read more
Is this what you are looking for? string[,] prop; //This is a 2D string List<List<string>> mysteryList; if (value is object[,]) { object[,] objArray = (object[,])value; // Get upper bounds for the array int bound0 = objArray.GetUpperBound(0);//index of last element for the given dimension int bound1 = objArray.GetUpperBound(1); prop = new string[bound0 + 1, bound1 + … Read more
Time for a crash course on arrays in C. First of all, let’s fix the initializer for the array: int a[3][4] = { { 1, 2, 3, 4}, { 5, 6, 7, 8}, { 9, 10, 11, 12} }; This defines a 3-element array of 4-element arrays of int. The type of the expression a … Read more
Iterate the outer array, then the inner arrays. Add each value to an indexed array in your result. foreach ($your_array as $sub_array) { foreach ($sub_array as $key => $value) { $result[$key][] = $value; } } solved PHP – Split Multidimensional Array by key/value
You could split the strings and use the parts as path to the nested array. var array = [‘catalog.product.name’, ‘catalog.product.description’, ‘catalog.product.status’, ‘catalog.product_attribute_set.name’, ‘catalog.product_attribute_set.type’], result = []; array.forEach(s => s .split(‘.’) .reduce((object, value) => { var item = (object.children = object.children || []).find(q => q.value === value); if (!item) object.children.push(item = { value, label: value }) … Read more
You have extra stars. The function should be void assign_memory_for_board(int ROWS, int COLS, int *** board) { *board = new int*[ROWS]; for (int i = 0; i < ROWS; i++) { (*board)[i] = new int[COLS]; } } 3 solved Allocate memory 2d array in function C++
In your example you are using the function strcmp to compare the integers, but this function is made to compare binary safe strings. You need to use another function or just an operator like >. So, your array has been sorted correctly by PHP. solved Usort multidimensional array in PHP isn’t working for me
It sounds like you want to group the items by league. Let’s use our array_reduce friend for that. This is the basic syntax: $arr = [ [ “leauge” => “sweeden”, “fixture” => “12” ], [ “leauge” => “sweeden”, “fixture” => “13” ], [ “leauge” => “germany”, “fixture” => “14” ], [ “leauge” => “france”, “fixture” … Read more
Didn’t tryed this, and I’m just guessing what you want to acomplish, but here it is: int[] arrayRow; int[] arrayCol; int[,] myArray = new int[Math.Max(arrayRow.Length, arrayCol.Length), 2]; for (int i = 0; i < arrayRow.Length; i++) myArray[i, 0] = arrayRow[i]; for (int i = 0; i < arrayCol.Length; i++) myArray[i, 1] = arrayCol[i]; solved Combining … Read more
Introduction This tutorial will provide a step-by-step guide on how to combine two single dimensional arrays into a two-dimensional array in C#. We will discuss the different methods of combining the two arrays, as well as the advantages and disadvantages of each approach. We will also provide code examples to illustrate the different approaches. By … Read more
Well, there are two different types: Array of array (jagged array): float[][] sample = new float[][] { new float[] {1, 2, 3}, new float[] {4, 5}, // notice that lines are not necessary of the same length }; 2d array: float[,] sample2 = new float[,] { {1, 2, 3}, {4, 5, 6}, }; Edit: your … Read more
Here’s an issue I found: int boardcounter = 1; //… for (int j = 0; j < 3; j++) { board[i][j] = (char) boardcounter; boardcounter++; } The issue is that the cast (char) does not convert the int variable into a textual representation. The cast actually converts the integer to smaller sized integer variable. There … Read more
If you’re looking to create a 2D array you should take a look at this Stack Overflow post here. It has a nice image to explain how 2D memory is laid out and how to properly create the array. Remember, when you create dynamic memory using new you need to delete the memory manually with … Read more
