$newArray = [];
foreach ($arr as $item) {
$items = explode('_', $item);
$newArray[$items[0]][$items[1]] = $item;
}
var_dump($newArray);
exit();
This should do the trick. You should have a look at the explode function

Another way to do this without foreach loop. :->
$arr = array('0_1','0_3','1_2','1_1','4_1');
$result = [];
array_walk($arr,function($v,$k)use (&$result){
$data = explode("_",$v);
$result[$data[0]][$data[1]] = $v;
});
print_r($result);

Thanks for your solution. but It seem the first solution is more readable and simple.
$arrv = array('0_1','0_3','1_2','1_1','4_1');
$newArray = [];
array_walk($arrv,function($value,$key){
global $newArray;
$indexArray = explode("_",$value);
$newArray[$indexArray[0]][$indexArray[1]] = $value;
});
var_dump($newArray);
