PHP check array object key value without using loop/foreach - php

Question

Just to learn more techniques in PHP , I'm so used in loop foreach and I want to find some other ways on how to check an array object. Let's say if we have a result something like this:
Array
(
[0] =; stdClass Object
(
[gallery_id] => 38
[artist_id] => 58
[title] => Appearances
[description] => Appearances
[photo_file] =>
[status] => 1
[insert_timestamp] => 2014-08-07 03:27:23
[update_timestamp] => 2014-08-07 15:26:24
[url] => talents/58/photos/38/Appearances
[position] =>
)
[1] => stdClass Object
(
[gallery_id] => 36
[artist_id] => 58
[title] => Endorsements
[description] => Endorsements
[photo_file] =>
[status] => 1
[insert_timestamp] => 2014-08-07 03:17:28
[update_timestamp] => 2015-01-13 15:50:09
[url] => talents/58/photos/36/Endorsements
[position] => 1
)
[2] => stdClass Object
(
[gallery_id] => 34
[artist_id] => 58
[title] => Magazine Covers
[description] => Magazine Covers
[photo_file] =>
[status] => 1
[insert_timestamp] => 2014-08-07 02:54:27
[update_timestamp] => 2015-01-13 15:50:10
[url] => talents/58/photos/34/Magazine-Covers
[position] => 2
)
)
I know we can do something like this to check a value in the object:
$myFlag = 2;
foreach($objArr as $obj){
if($obj->position == $myFlag){
return true;
}
}
But is there a way to check it without using a loop? A more efficient way, coz I feel whenever I use this(most of the time) , It's not that efficient and somehow takes time to process.

Answer 1

How about using array_filter with closure.
$myFlag = 2;
$target = array_filter($objArr, function($elem) use($myFlag){
return $elem->position === $myFlag;
});
print_r($target);
result is ...
Array
(
[2] => stdClass Object
(
[gallery_id] => 34
[artist_id] => 58
[title] => Magazine Covers
[description] => Magazine Covers
[photo_file] =>
[status] => 1
[insert_timestamp] => 2014-08-07 02:54:27
[update_timestamp] => 2015-01-13 15:50:10
[url] => talents/58/photos/34/magazine-covers
[position] => 2
)
)
