returning to php after a VERY long break and need some help. So my function is returning the following array. I now want to get the 'id' and 'name' and return them in their own array where name is the key and id is the value. How would I go about it?
object(stdClass)#11 (1) {
["data"]=>
array(5) {
[0]=>
object(stdClass)#1 (3) {
["id"]=>
string(36) "7fd134a2-5f80-4d07-8a1a-a54c48f7e71b"
["type"]=>
string(13) "userattribute"
["attributes"]=>
object(stdClass)#2 (1) {
["name"]=>
string(10) "Test1Test1"
}
}
[1]=>
object(stdClass)#3 (3) {
["id"]=>
string(36) "dcdd87d5-1ff3-4fd9-8a75-7e20fe8f19d7"
["type"]=>
string(13) "userattribute"
["attributes"]=>
object(stdClass)#4 (1) {
["name"]=>
string(10) "Test1Test2"
}
}
[2]=>
object(stdClass)#5 (3) {
["id"]=>
string(36) "b167b703-a63f-4548-9104-43a436871f45"
["type"]=>
string(13) "userattribute"
["attributes"]=>
object(stdClass)#6 (1) {
["name"]=>
string(10) "Test1Test3"
}
}
[3]=>
object(stdClass)#7 (3) {
["id"]=>
string(36) "6a17046b-b665-493f-83be-35e0a9129c49"
["type"]=>
string(13) "userattribute"
["attributes"]=>
object(stdClass)#8 (1) {
["name"]=>
string(10) "Test1Test4"
}
}
[4]=>
object(stdClass)#9 (3) {
["id"]=>
string(36) "4704cf6f-1c8b-432e-88df-f6865c8690d5"
["type"]=>
string(13) "userattribute"
["attributes"]=>
object(stdClass)#10 (1) {
["name"]=>
string(10) "Test1Test5"
}
}
}
}

Use array_column() to extract each column, and array_combine() to merge them so one is the key and the other is the value of an associative array.
$result = array_combine(array_column($object->data, 'id'), array_column($object->data, 'name'));
where $object is the variable holding the data you posted.
