I have an multidimensional array like this, but I just only need some index to be displayed.
Array
Array
(
[0] => Array
(
[1] => 220
[38] => 200
[232] => 970
)
[1] => Array
(
[0] => 220
[2] => 190
[39] => 200
)
[2] => Array
(
[1] => 190
[3] => 40
[50] => 220
)
[3] => Array
(
[2] => 40
[4] => 200
[57] => 120
)
)
then i just want to display only index [1] and [3], so it would be like this
Array
(
[1] => Array
(
[0] => 220
[2] => 190
[39] => 200
)
[3] => Array
(
[2] => 40
[4] => 200
[57] => 120
)
)
i try using this code
$order = array(1,3);
uksort($graph, function($key1, $key2) use ($order) {
return (array_search($key1, $order) > array_search($key2, $order));
});
but still, it's displayed the rest array that I don't need ([0] and [2]).
Like this:
foreach(array_keys($graph) as $key)
{
if($key == 0|| $key == 2)
{
unset($graph[$key]);
}
}
print_r
Array
(
[1] => Array
(
[0] => 220
[2] => 190
[39] => 200
)
[3] => Array
(
[2] => 40
[4] => 200
[57] => 120
)
)
