如何在一维数组中分配键名

Question

I'm trying to assign country code as key, country name as value. The following is my code, if any wrong please correct me.

$return = array();
foreach($result as $key=>$value){
    array_splice($return, count($return),0, array($value['country_code']=>$value["name"]));
}

Answer 1

it looks like this would suffice:

$return = array_column($result, 'name', 'country_code');

this is essentially a shorter version of

foreach($result as $key => $value){
    $return[$value['country_code'] ] = $value["name"];
}

Answer 2

Iterate the $result to set the value.

foreach($result as $v)
{
  $return[$v['country_code']] = $v['name'];
}

Answer 3

here one more approach using array_map() :

$modified = array_map(function($result){    
    return [$result['country_code'] => $result['name']];
}, $resultset);

Cheers!
