PDO fetch obj with defined objectname - php

Question

Similar too:
PDO::FETCH_CLASS | PDO::FETCH_CLASSTYPE
I want to do the same with:
PDO::FETCH_OBJ
Means I want to pick each row as an object named by the first value.
Example:
id name url
1 Test www.test.de
2 Test2 www.test2.de
Select name, id, url FROM whatever;
$processes = $result->fetchAll(PDO::FETCH_OBJ);
returns the objects idexed from 0 - x
fetchAll(PDO::FETCH_ASSOC | PDO::FETCH_GROUP)
Returns it nearly like I want just 2 downsides:
test {
0: [
'id': 1,
'src': 'www.test.de'
]
}
First is I want to keep name in the object (could douple select (select name, name ...) and I have the unecessary array inside.
So any idea how I get it to this:
test [
'name': 'test',
'id': 1,
'src': 'www.test.de'
]
test2 [
'name': 'test2',
'id': 2,
'src': 'www.test2.de'
]

You can use this:
$dbh = new PDO('mysql:dbname=my;host=localhost', 'root', '');
$sth = $dbh->prepare("SELECT name, id, name, url FROM data");
$sth->execute();
var_dump($sth->fetchAll(PDO::FETCH_OBJ | PDO::FETCH_GROUP | PDO::FETCH_UNIQUE));
The output will be like this:
array(3) {
'test 1' =>
class stdClass#6 (3) {
public $id =>
string(1) "4"
public $name =>
string(6) "test 1"
public $url =>
string(13) "www.gmail.com"
}
'test 2' =>
class stdClass#4 (3) {
public $id =>
string(1) "2"
public $name =>
string(6) "test 2"
public $url =>
string(14) "www.google.com"
}
'test 3' =>
class stdClass#5 (3) {
public $id =>
string(1) "3"
public $name =>
string(6) "test 3"
public $url =>
string(21) "www.stackoverflow.com"
}
}
But be noticed: if you add duplicate values into the name column, you will get values of last record with the same name. In my example above I have table with this dataset:
select * from data;
+----+--------+-----------------------+
| id | name | url |
+----+--------+-----------------------+
| 1 | test 1 | www.ya.ru |
| 2 | test 2 | www.google.com |
| 3 | test 3 | www.stackoverflow.com |
| 4 | test 1 | www.gmail.com |
+----+--------+-----------------------+
4 rows in set (0,00 sec)
So you have data from record with ID = 4 in object named "test 1".
