问题 I already read hundreds of posts here about it but none is adapted to my simple needs. NOOB ALERT . I'm trying to have a notification in my app choose from a list of activities and open one of them randomly but without repetition, I was able to have a randomized effect but some activities pop up many times and others don't. So basically what I need is to go over all the activities on the list randomly, and when all of them have been visited, re-shuffle the list and start over Here's a little

Shuffling an array

由 给你一囗甜甜゛ 提交于 2019-12-12 01:54:55
问题 What this code is supposed to do is shuffle an array, nonetheless every time I run it on a I get the same "shuffled" array (of course by inputting the same un-shuffled array) I thought the srand(time(NULL)); part was going to make sure of that. If that is not it I don’t know how to make it really shuffle it. So to sum up I need to know why my code is shuffling the array the same way every time. # include <stdio.h> # include <stdlib.h> # include <math.h> # include <time.h> int main(){ int n;

How to shuffle my Array or String list in a more readable way?

由 懵懂的女人 提交于 2019-12-11 19:31:21
问题 Imagine you want to have a very readable, easily editable list of items, separated by comma's only, and then echo 3 random items from that list. Array or string doesnt matter. For now, I got the following working (Thanks webbiedave!) $fruits = array('Mango', 'Banana', 'Cucumber', 'Pear', 'Peach', 'Coconut'); $keys = array_rand($fruits, 3); // get 3 random keys from your array foreach ($keys as $key) { // cycle through the keys to get the values echo $fruits[$key] . "<br/>"; } Outputs: Coconut
