PHP Random Number Generator Using Array and substr

php

Solution

You can use `array_slice` to get 6 numbers from the array:

<?php
$numbers = range(1, 49);
shuffle($numbers);
$numbers = array_slice($numbers, 0, 6);
print_r($numbers);
?>

Problem

I'm trying to build a simple lottery number generator for my own amusement. I have to pick six numbers between 1 & 49, obviously without repeats. I have tried using the `mt_rand` feature for six different variables then echoing them in order, but I guess there is the possibility of repeated numbers. So now I'm trying to get the following to work. ``` <?php $randomString = substr(shuffle("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31","32","33","34","35","36","37","38","39","40","41","42","43","44","45","46","47","48","49"), 0, 6); echo $randomString; ?> ``` I know that substr is for strings and not arrays but I can't find the alternative. Anyone got a solution?
