How to arrange numbers in ascending order in php with if statement?

Question

So I have this:

$x=rand(0,100);
$y=rand(0,100);
$z=rand(0,100);

How can I put them in increasing order?

Add those number to an array, then sort the array using `asort()` — , Mar 15 '19 at 17:09
`$x=rand(0,33); $y=rand(34,66); $z=rand(67,100);` should work. — MonkeyZeus, Mar 15 '19 at 17:15
@MonkeyZeus that doesn't guarantee the same result though. You can't get `x=1` `y=2` `z=3` — Sam, Mar 15 '19 at 17:25

$array = [rand(0,100), rand(0,100), rand(0,100)];
sort($array);
list($x, $y, $z) = $array;

As your questions reads like a homework I'll show you some code that generates the expected result but won't be a valid due.

$x = rand(0,100);
$y = rand(0,100);
$z = rand(0,100);

$numbers = [$x, $y, $z];

usort($numbers, function($left, $right) {
    return $left <=> $right;
});

array_walk($numbers, function($val) {
    echo $val . PHP_EOL;
});

If you are using PHP7, they introduced the Spaceship Operator which could be useful for you.

What is <=> (the 'Spaceship' Operator) in PHP 7?

Update: There is actually a much easier answer than that. Put them in an array and use sort() on the array; http://php.net/manual/en/function.sort.php
