PHP - Merge looped arrays into one

Question

I have two result set from database first one is :

Array(
    [0] => Array([vehicle] => BUS NO.1 )
    [1] => Array([vehicle] => BUS NO.2)}

second one is :

Array([0] => Array(
            [trip_name] => Trip00011
            [running_km] => 5000)
      [1] => Array(
            [trip_name] => Trip00021
            [running_km] => 2400))

I want to merge these arrays like following array:

Array([0] => Array(
            [vehicle] => BUS NO.1
            [trip_name] => Trip00011
            [running_km] => 5000 )
        [1] => Array(
            [vehicle] => BUS NO.2
            [trip_name] => Trip00011
            [running_km] => 5000)
        [2] => Array(
            [vehicle] => BUS NO.1
            [trip_name] => Trip00021
            [running_km] => 2400 )
        [3] => Array(
            [vehicle] => BUS NO.2
            [trip_name] => Trip00021
            [running_km] => 2400))

Actually, this is my question.Could you please help me to do this

Have you looked at the [array_merge](http://php.net/manual/en/function.array-merge.php) page of the PHP documentation? — Peppermintology, Sep 14 '18 at 09:48
yes, but this is not two arrays. looped arrays of one array. — Miya, Sep 14 '18 at 09:52
`this is not two arrays. looped arrays of one array` - Well thats not quite the question you asked, perhaps you could elaborate in your question. — Peppermintology, Sep 14 '18 at 09:56
If you just want to add all your result from 2 array in one array in not particular order : just create a new array, one foreach on first array and add result on result array, then foreach on second array and add result on result array...did you try something? — Mickaël Leger, Sep 14 '18 at 09:56
Just use the `+` operator to add your two Arrays...Or array_merge as said above... — Elementary, Sep 14 '18 at 10:08
@Elementary it's better to use `array_merge` than `+`, because plus operator will skip duplicated keys — Agnius Vasiliauskas, Sep 14 '18 at 10:43

Given these following arrays

$array1=Array(
            0 => Array('vehicle' => 'BUS NO.1' ),
            1 => Array('vehicle' => 'BUS NO.2')
        );

$array2=Array(
            0 => Array(
                'trip_name' => 'Trip00011',
                'running_km' => 5000),
            1 => Array(
                'trip_name' => 'Trip00021',
                'running_km' => 2400)
        );

You can obtain the expected output using either the simplest way

foreach($array2 as $val){
        foreach($array1 as  $v){
             $result[]=$v+$val;
        }
    }

or the complex(maybe the worst) way:

!($result=[])?array_map(function($a) use ($array1,&$result){ $result=array_merge($result,array_map(function($val)use($a){ return $val+$a;},$array1));},$array2):[];

ouput:

array(4) {
  [0]=>
  array(3) {
    ["vehicle"]=>
    string(8) "BUS NO.1"
    ["trip_name"]=>
    string(9) "Trip00011"
    ["running_km"]=>
    int(5000)
  }
  [1]=>
  array(3) {
    ["vehicle"]=>
    string(8) "BUS NO.2"
    ["trip_name"]=>
    string(9) "Trip00011"
    ["running_km"]=>
    int(5000)
  }
  [2]=>
  array(3) {
    ["vehicle"]=>
    string(8) "BUS NO.1"
    ["trip_name"]=>
    string(9) "Trip00021"
    ["running_km"]=>
    int(2400)
  }
  [3]=>
  array(3) {
    ["vehicle"]=>
    string(8) "BUS NO.2"
    ["trip_name"]=>
    string(9) "Trip00021"
    ["running_km"]=>
    int(2400)
  }
}

Please check my result array thoroughly which results four inner arrays — Miya, Sep 14 '18 at 11:07

you can use array_merge. array_merge(array1, array2)

Are you sure? Have you even tried to run `array_merge` on the given examples? – Nico Haase Sep 14 '18 at 10:52
