Question

    $arr = [
        (Object)[
            'interval' => "2018-08-26",
            'product_id' => 12 ,
 'size' => 10 
        ],
        (Object)[
            'interval' => "2018-09-26",
            'product_id' => 26 ,
'size' => 25 
        ],
        (Object)[
            'interval' => "2018-07-26",
            'product_id' => 50 ,
'size' => 28 
        ],(Object)[
            'interval' => "2018-08-26",
            'product_id' => 60,
'size' => 89 
        ],
        (Object)[
            'interval' => "2018-12-26",
            'product_id' => 75,
'size' => 89 
        ],
        (Object)[
            'interval' => "2018-09-26",
            'product_id' => 98 ,
'size' => 89 
        ] 
    ];

I need only 12 and 60 product id. How can filter from this array (as only they has interval of Aug (08)).

id 16 doesnt exist in your array – Kamil Kiełczewski Feb 05 '19 at 12:28 — Kamil Kiełczewski, Feb 05 '19 at 12:28
What produced the output in your code example? – marekful Feb 05 '19 at 12:31 — marekful, Feb 05 '19 at 12:31
@KamilKiełczewski its typo mistake this is 60 product id – Pritesh Mahajan Feb 05 '19 at 12:33 — Pritesh Mahajan, Feb 05 '19 at 12:33
Did you try anything? Even a simple foreach loop? – RiggsFolly Feb 05 '19 at 12:37 — RiggsFolly, Feb 05 '19 at 12:37

If your input are IDs and you want to get dates then try

$ids = [12,60];

$result = array_filter($arr, function($e) use($ids) {
    return in_array($e->product_id, $ids);
});

$dates = array_map(function($e) { return $e->interval; }, $result );

working example here

UPDATE

If your input is month number e.g. 08 and you wana to get IDs then try this

$result = array_filter($arr, function($e) {
    return substr($e->interval,5,2) == '08';
});

$ids = array_map(function($e) { return $e->product_id; }, $result );

working example here. The $result contains full objects so you can read project_is as well as size.

Better define `$ids = [60,12]` and add `use ($ids)` and `in_array($e->product_id, $ids)` - but that just me... – dWinder Feb 05 '19 at 12:37
you are correct but i need to get data from date not ids – Pritesh Mahajan Feb 05 '19 at 12:42
@PriteshMahajan I update answer – Kamil Kiełczewski Feb 05 '19 at 12:47
i don't want to use ids :( @KamilKiełczewski – Pritesh Mahajan Feb 05 '19 at 12:48
@PriteshMahajan If you don't want to use ids then you can use this return statement array filter: `return $e->product_id == 60 or $e->product_id==12;` and remove string `use($ids)` after function – Kamil Kiełczewski Feb 05 '19 at 12:50

try this:

$arrays = array_filter($arrays,function($arr){
  return substr($arr->interval,5,2) == '08';
});

array_walk($arrays,function($obj){
  unset($obj->interval);
});
