I can't sort my array so that numbers comes before - (hyphen).
My array today:
Array
(
[-] => Test
[0] => Test
[1] => Test
[2] => Test
)
The order I want:
Array
(
[0] => Test
[1] => Test
[2] => Test
[-] => Test
)
I have searched both here and on Google. But found no answers. I have tried experimenting with ksort() and usort(), but without success.
You could create your own compare function with uksort which handels such special cases.
uksort($a, function($a, $b) {
if (is_numeric($a) && is_numeric($b)) return $a - $b;
else if (is_numeric($a)) return -1;
else if (is_numeric($b)) return 1;
return strcmp($a, $b);
});
Use natural order sorting function
natsort()
example:
$arr = ['_', 6, 3, 5];
natsort($arr);
print_r($arr);
output:
Array
(
[2] => 3
[3] => 5
[1] => 6
[0] => _
)
If you want to sort by keys then you can use ksort() function with flag SORT_NATURAL ksort($arr, SORT_NATURAL);
example:
$arr = [
'_' => 'test',
6 => 'test',
3 => 'test',
5 => 'test'
];
ksort($arr, SORT_NATURAL);
function check($x, $y){
if(is_numeric($x) && !is_numeric($y))
return 1;
else if(!is_numeric($x) && is_numeric($y))
return -1;
else
return ($x < $y) ? -1 : 1;
}
$array = array("-", "1", "2", "3");
usort ( $array , 'check' );
