I have an object like this in PHP-
array(2) { [0]=> object(stdClass)#1869 (10) { ["id"]=> string(1) "1" ["country"]=> string(7) "Austria" ["cat_one"]=> string(7) "#FFCB69" } [1]=> object(stdClass)#1868 (10) { ["id"]=> string(1) "2" ["country"]=> string(7) "Belgium" ["cat_one"]=> string(7) "#FFCB69" } }
I would like to take the country property and set it as the key of each values in the root object. A foreach resets the whole object value on each keys. Intended result is similar to the one right below –
array(2) { [Austria]=> object(stdClass)#1869 (10) { ["id"]=> string(1) "1" ["cat_one"]=> string(7) "#FFCB69" } [Belgium]=> object(stdClass)#1868 (10) { ["id"]=> string(1) "2" ["cat_one"]=> string(7) "#FFCB69" } }

Answer
As array_column
can extract public property from objects, which are elements of arrays, you can:
$array = []; // your initial array print_r( array_combine( // extract country property from each object array_column($array, 'country'), $array ) );
But this method does not remove country
property from each object.
