Sorting PHP Randomised numbers by size

Question

So I've got this:

$h = $user_goals;

while($h > 0) {
randomScorer();
$minute = rand(0,90);
echo "(".$minute.")<br>";

$h--;

Basically, what it does is, $user_goals, has a load of factors drawn into it and creates a number, between 0-5, and this information is used to generate the times of the goals, using the above PHP function.

It's working, it's brilliant, etc. However, the numbers are appearing in random order in which they are generated and so I was wondering:

Is there any way to sort these numbers?

Would I put them into an array during this iteration methodology, and then sort the array by the number's value?

Any help is greatly appreciated!

That is why PHP provides us Sort functions. Have a look here.

<?php

$fruits = array("lemon", "orange", "banana", "apple");
sort($fruits);

?>

Since your array is NUMERIC, you need to use the FLAG along with the sort function.

sort($goals, SORT_NUMERIC); 
print_r($goals);

So I'd have to add them into an array, say let's call it goals, and then use that sort method, then post the array, one by one, adding the function for the name of the scorer infront of this? Right? – Bate Wes Sep 15 '13 at 03:14
yeah. `sort($goals)` will suffice. – Shankar Narayana Damodaran Sep 15 '13 at 03:15
Thanks man! much appreciated, will check that this works and then give you that tick :) – Bate Wes Sep 15 '13 at 03:17
Yeah and don't forget to add the NUMERIC flag. – Shankar Narayana Damodaran Sep 15 '13 at 03:18

Same idea, using sort() but also uses range and array_walkto set up your array a little closer to how you already do it:

$goal_array = range(1, $user_goals); // Warning, assumes $user_goals is number

array_walk($goal_array, function(&$goal) {
   randomScorer();
   $goal = rand(0,90);
});

sort($goal_array, SORT_NUMERIC);
