PHP 2d Array Push Issue

Question

I'm in a bind..

This is the output I would like;

Array
(
[country] => Array(
                    [0] => England
                    [1] => Channel Islands
                )
[gor] => Array(
                    [0] => North East
                    [1] => North West
                )
[parliamentaryconstituency] => Array(
                    [0] => Aldershot
                    [1] => Aldridge-Brownhills
                )
)

This is what I currently have;

Array
(
[0] => Array
    (
        [country] => England
    )
[1] => Array
    (
        [country] => Channel Islands
    )
[2] => Array
    (
        [gor] => North East
    )
[3] => Array
    (
        [gor] => North West
    )
[4] => Array
    (
        [parliamentaryconstituency] => Aldershot
    )
[5] => Array
    (
        [parliamentaryconstituency] => Aldridge-Brownhills
    )
)

My code is;

foreach ($input as $key => $value) {
    foreach ($value as $subkey => $subvalue) {
        switch ($key)
        {
            case 'country':
                $country = Country::description($subvalue)->get()->first();
                array_push($new_input, array('country' => $country->description));
              break;                    
            case 'gor':
                $gor = Gor::description($subvalue)->get()->first();
                array_push($new_input, array('gor' => $gor->description));
              break;
            case 'parlc':
                $parliamentaryconstituency = ParliamentaryConstituency::description($subvalue)->get()->first();
                array_push($new_input, array('parliamentaryconstituency' => $parliamentaryconstituency->description));
              break;
        }
    }
}

I considered array_push($new_input['country'], $country->description); and having $new_input['country'] above the foreachs but that will output an empty country array if no countries are selected and I'd prefer it not to appear at all if that's the case.

You could try this one:

$result = array();
foreach ($input as $key => $value) {
    foreach ($value as $subkey => $subvalue) {
        switch ($key)
        {
            case 'country':
                $country = Country::description($subvalue)->get()->first();
                if ($country) {
                    $result['country'][] = $country;
                }
                break;
            case 'gor':
                $gor = Gor::description($subvalue)->get()->first();
                if ($gor) {
                    $result['gor'][] = $gor;
                }
                break;
            case 'parlc':
                $parliamentaryconstituency = ParliamentaryConstituency::description($subvalue)->get()->first();
                if ($parliamentaryconstituency) {
                    $result['parliamentaryconstituency'][] = $parliamentaryconstituency;
                }
                break;
        }
    }
}
print_r($result);

array_push always add a new element at the end of the array. Instead, initialize the array with all the keys like this

$result = array("country" => array(), "gor" => array(), etc);

And in your loop assuming the value you want to insert is in $value do

$result[$key][] = $value

Or if you prefer using array_push

array_push($result[$key], $value);

'$list=array();'


/add array value
'array_push($list,array("name"=>"jone","surname"=>"doe"));'

//get array value
'$list[index][columnname]'
