Ds\Sequence::sort — Sorts the sequence in-place
Sorts the sequence in-place, using an optional comparator
function.
comparator
The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.
No value is returned.
Example #1 Ds\Sequence::sort() example
<?php
$sequence = new \Ds\Vector([4, 5, 1, 3, 2]);
$sequence->sort();
print_r($sequence);
?>
The above example will output something similar to:
Ds\Vector Object ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )
Example #2 Ds\Sequence::sort() example using a comparator
<?php
$sequence = new \Ds\Vector([4, 5, 1, 3, 2]);
$sequence->sort(function($a, $b) {
return $b <=> $a;
});
print_r($sequence);
?>
The above example will output something similar to:
Ds\Vector Object ( [0] => 5 [1] => 4 [2] => 3 [3] => 2 [4] => 1 )
