using array merge into a foreach loop - php

Question

I need to merge a new array of alternative information into the loop if they have the alternative information in their profile.
Here's my loop:
foreach ($doctor->getVars() as $k => $v)
{
$data['doctor_'. $k] = $v;
}
foreach ($patient->get_data() as $k=>$v)
{
if (is_string($v) || is_numeric($v))
$data["patient_" . $k] = strtoupper($v);
}
Here's the $data var_dump:
Array
(
[employee] => person
[date] => 05/08/2013
[datetime] => 05/08/2013 9:41:15 AM
[department] => stuff
[employee_ext] => 7457
[employee_email] =>
[barcode] => *NZS01*
[doctor_df_code] => 09HQ
[doctor_npi] => 1111111111
[doctor_dea] => B4574
[doctor_upin] =>
[doctor_license] =>
[doctor_phone] => [phone]
[doctor_fax] => [phone]
[doctor_fname] => UNDEFINED
[doctor_lname] => UNDEFINED
[doctor_title] =>
[doctor_intake_rx_caller_id] =>
[doctor_costco_rx_caller_id] =>
[doctor_reorder_rx_caller_id] =>
[doctor_address1] => 24 CABELL st
[doctor_address2] => SUITE 10
[doctor_city] => places
[doctor_state] => CA
[doctor_zip] => 91111
[doctor_active_events] =>
[doctor_dont_call] => 0
[doctor_dont_fax] => 1
)
I need to merge the below array into the above array.
Here's the print var for the function addr($dfcode):
Array
(
[0] => Array
(
[CODE_] => 09HQ
[doctor_address1] => alternate addy
[doctor_address2] => 45854
[doctor_city] => different city
[doctor_state] => CA
[doctor_zip] => 963545
[doctor_phone] => [phone]
[doctor_fax] => [phone]
)
)
I'm new to array merge and I'm assuming right after the $data['doctor_'. $k] = $v i could list out the new function and the fields i want to merge in particular?
syntax is what i'm not sure on:
$data['doctor_'. $k] . array_merge(addr($dfcode))['doctor_address1'] = $v;
Any help would be greatly appreciated, thank you.

The general formula for merging two arrays is as follows (merging $array_m into $array_o):
foreach($array_m as $key=>$value){
$array_o[$key] = $value;
}
$array_o would now contain all of the elements of $array_m
EDIT: I just noticed in your post that you seem to want to use the array_merge function. You could also do the following:
$array_o = array_merge($array_o, array_m);
