[edm] => 1
)
)
I'm trying array_push function and also use foreach but isn't working .
Please suggest how can i do this.

Answer 1

The solution using array_merge function and conversion(casting) from array into object and vice versa(only for basic stdClass objects):
// $array1 is your first array with 'main' key
// $array2 is your second array with 'dt' key
$main_arr = (array) current($array1['main']); // converting object into array
$merged = array_merge($main_arr, $array2['dt']); // combining "properties"
$array1['main'] = [(object) $merged]; // saving object with additional properties back to the initial array
print_r($array1); // will give the expected output

[0] => stdClass Object
What you have under index 0 is not an array, but object. Unless it implements ArrayAccess interface, you cannot do this as you'd with regular array.

Answer 3

Assuming $big_array is the first array you posted and $small_array is the second array you posted then this should work:
$big_array['main'][0] = (object)array_merge((array)$big_array['main'][0], $small_array['dt']);
I dunno what your code looks like so this one might work automatically for you:
$main[0] = (object)array_merge((array)$main[0], $dt);
Per Marcin Orlowski's comment, below is the proper way to do this without the risk of overriding any classes or methods:
$main[0]->dtm = $dt['dtm'];
$main[0]->edm= $dt['edm'];
