$arr1 = array(1,2,3);
$arr2 = array("a","b","c");
$arr3 =array("1a","2b","3c");
How can I do the following ?
$one = 1,a,1a
$two = 2,b,2b
$three = 3,c,3c

Use array_map() function to map through all arrays at the same time. Like this :
$array_merged = array_map(function($v1,$v2,$v3) {
return $v1 . ','. $v2 . ',' . $v3;
}, $arr1, $arr2, $arr3);
/*
Array (
[0] => "1,a,1a",
[1] => "2,b,2b",
[2] => "3,c,3c",
)
*/

very clean solution +1
You can try this:
$arr1 = array(1,2,3);
$arr2 = array("a","b","c");
$arr3 = array("1a","2b","3c");
$i = 0;
foreach ($arr1 as $key => $value) {
$newArr[] = $value.",".$arr2[$i].",".$arr3[$i];
$i++;
}
echo implode("<br/>", $newArr);
Result:
1,a,1a
2,b,2b
3,c,3c
You can also perform this by using for loop.

you are welcome, now chose the best answer and mark as accepted because its very important for other who still facing this issue.
Try this:
$arr1 = [1,2,3];
$arr2 = ["a","b","c"];
$arr3 = ["1a","2b","3c"];
$matrix = [$arr1, $arr2, $arr3];
var_dump(transpose($matrix));
function transpose($matrix) {
return array_reduce($matrix, function($carry, $item) {
array_walk($item, function ($value, $key) use (&$carry) {
$carry[$key][] = $value;
});
return $carry;
});
}
