php merging two arrays into one - php

Question

I have two arrays that need to be merged together and trying to figure out the correct way of doing it.
this is the first array
Array
(
[IndividualOutmsg] => Array
(
[0] => Array
(
[user_id] => 3
[number] => 414566765
[msg] => some message
)
[1] => Array
(
[user_id] => 3
[number] => 410335509
[msg] => any message
)
)
)
this is the second array:
Array
(
[0] => Array
(
[0] => OK
[1] => 0
[2] => d142b46128b869d0
[3] => 6178977058476937
)
[1] => Array
(
[0] => OK
[1] => 0
[2] => 60f403f4e243e684
[3] => 6198708709873543
)
)
what i want to get is this:
Array
(
[IndividualOutmsg] => Array
(
[0] => Array
(
[user_id] => 3
[number] => 414566765
[msg] => some message
[sms_status] => OK
[error_code] => 0
[msg_id] => d142b46128b869d0
[msg_id_2] => 6178977058476937
)
[1] => Array
(
[user_id] => 3
[number] => 410335509
[msg] => any message
[sms_status] => OK
[error_code] => 0
[msg_id] => 60f403f4e243e684
[msg_id_2] => 6198708709873543
)
)
)

Answer 1

In that format, you really have to do a lot of the legwork yourself and can't just use array_merge to combine the arrays. It would have to be a more custom job, like so:
$count = count($second_array);
for($i=0; $i<$count; $i++){
$first_array['IndividualOutmsg'][$i]['sms_status'] = $second_array[0];
$first_array['IndividualOutmsg'][$i]['error_code'] = $second_array[1];
$first_array['IndividualOutmsg'][$i]['msg_id'] = $second_array[2];
$first_array['IndividualOutmsg'][$i]['msg_id2'] = $second_array[3];
}
If you were to output the second array with the associative keys set, it would be much easier to combine them using array_merge, provided the keys didn't conflict.
$count = count($second_array);
for($i=0; $i<$count; $i++){
$first_array['IndividualOutmsg'][$i] =
array_merge($first_array['IndividualOutmsg'][$i], $second_array[$i]);
}

Array merge might be what you're looking for...
Though you'll need to probably write a loop or function that can get to the right place in your multi-dimensional array, perform the merge and also change the relevant keys.
