mysql - Eloquent (Laravel) query in many to many relation -

i have many many relation(eloquent laravel) , want filter item tags.

table_item        table_item_tag       table_tag id  name       id  item_id  tag_id       id  name 1  item       1    1        1          1   tag 2  item b       2    1        2          2   tag b                 3    2        1 

filter result should this: `

filter: name:tag a&b : sum of item 1         name:tag :   sum of item 1 

any ideas on how query should like? ive been struggling sum of items have both tags

assuming eloquent relations set properly, want along these lines:

$tags = ['tag a', 'tag b']; // or input or wherever  item::wherehas('tags', function ($q) use ($tags) {     foreach ($tags $tag) {         $q = $q->where('name', $tag);     } })->get();
