如何在单维数组中指定键名

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"];
}
