It only provides new ideas with low efficiency.

array(3) {  [0]=>  array(2) {    ["id"]=>    string(2) "79"    ["name"]=>    string(1) "a"  }  [1]=>  array(2) {    ["id"]=>    string(2) "78"    ["name"]=>    string(1) "b"  }  [2]=>  array(2) {    ["id"]=>    string(2) "36"    ["name"]=>    string(1) "c"  }}

$ar = array (  0 =>   array (    'id' => '79',    'name' => 'a',  ),  1 =>   array (    'id' => '79',    'name' => 'a',  ),  2 =>   array (    'id' => '78',    'name' => 'b',  ),  3 =>   array (    'id' => '36',    'name' => 'c',  ),);foreach($ar as $k=>$f) {  foreach($ar as $p=>$t) if($k != $p && $f == $t) unset($ar[$k]);}print_r($ar);

Array(    [1] => Array        (            [id] => 79            [name] => a        )    [2] => Array        (            [id] => 78            [name] => b        )    [3] => Array        (            [id] => 36            [name] => c        ))

If there are only duplicate IDs, how can I remove the duplicate names?

Then you have the #2 code.
But strictly speaking, this is not "de-duplication", but "clustering"
Only one data set in the same group is used.

Can I directly filter out duplicates during query?

Select distinct ('id') AS 'id', name FROM 'table'

Select distinct ('id') AS 'id', name FROM 'table'

This is my SQL statement. I cannot change it. could you change it for me? thank you.
$ SQL = "select t3.width as width, t3.height as height, t1.add _ time as add_time, t1.add _ author as add_author, t1.image _ url as image_url, t1.id as id, t1.browse _ real_cnt as browse_real_cnt from comments as t2 left join ornamentations as t1 on t1.id = t2.object _ id left join operations as t3 on t3.ornamentation _ id = t1.id where (t2.uid = $ id) AND (t1.enable = '0') order by id desc LIMIT 0, 5 ";

Which of your fields have already exists?
