how to arrange text/floats in ascending order


shadd

Recommended Posts

i have a set of numbers that i need to arrange in ascending order:

1.1.51,1.1.51.10,1.1.51.2,1.1.51.3,1.1.51.4,..........,A,1.1.52

my problem is that 1.1.51.10 is not coming at position A where it should.

how can i achieve this??

Perhaps...

$a = explode(',', '1.1.51,1.1.51.10,1.1.51.2,1.1.51.3,1.1.51.4,A,1.1.52'); 
echo 'original <pre> ' . print_r($a, 1) . '</pre>';

sort($a);
echo 'after sort() <pre> ' . print_r($a, 1) . '</pre>';

natsort($a);
echo 'after natsort() <pre> ' . print_r($a, 1) . '</pre>';

giving...

original
 Array
(
    [0] => 1.1.51
    [1] => 1.1.51.10
    [2] => 1.1.51.2
    [3] => 1.1.51.3
    [4] => 1.1.51.4
    [5] => A
    [6] => 1.1.52
)
after sort()
 Array
(
    [0] => 1.1.51
    [1] => 1.1.51.10
    [2] => 1.1.51.2
    [3] => 1.1.51.3
    [4] => 1.1.51.4
    [5] => 1.1.52
    [6] => A
)
after natsort()
 Array
(
    [0] => 1.1.51
    [2] => 1.1.51.2
    [3] => 1.1.51.3
    [4] => 1.1.51.4
    [1] => 1.1.51.10
    [5] => 1.1.52
    [6] => A
)
