If you have special conditions it is good to use uasort function. It lets you to define you own condition for ordering. It is easy - refer to its documentation. – Kancho Iliev Dec 20 '17 at 06:42

If you setup your array with strings, you can use natsort function to get result you want
$numbers = array('1', '2', '3', '3.1', '3.2', '3.3', '3.10', '3.11');
natsort($numbers);
print_r($numbers);
Now, when you init array with numbers, there is no difference between 3.10 and 3.1

You can use sort() function
$numbers = array(1, 2, 3, 3.1, 3.2, 3.3, 3.10, 3.11);
sort($numbers);
var_dump($numbers);

You just need to use sort() function.
For e.g.
$numbers = array(1, 2, 3, 3.1, 3.2, 3.3, 3.10, 3.11);
sort($numbers);
print_r($numbers);
Output: 1 2 3 3.1 3.2 3.3 3.10 3.11

Your float number have unequal decimal points, you need to keep all float values in same decimal point. eg. php doesn't consider trailing 0's in decimal point, you have to make your 3.1 to 3.01, 3.2 to 3.02 likewise. Then use sort you'll get your answer. – Sandesh Mule Dec 20 '17 at 11:23
