1 2 3 4 5 6 7 | <?php $a = ['a1', 'a2', 'a3']; $b = ['b1', 'b2', 'b3', 'b4', 'b5']; $combo = array_filter(array_merge(...array_map(null, $a, $b))); var_dump($combo); |
array(8) {
[0]=> string(2) "a1"
[1]=> string(2) "b1"
[2]=> string(2) "a2"
[3]=> string(2) "b2"
[4]=> string(2) "a3"
[5]=> string(2) "b3"
[7]=> string(2) "b4"
[9]=> string(2) "b5"
}
