To expand on Vince0789 's answer...

$remove looks to contain an array of arrays and not just an id string.

For example, $remove may be layed out as below;

[
    [ 
         'id' => 1,
         'content' => "Foo"
    ],
    [ 
         'id' => 2,
         'content' => "Bar"
    ],
]

What you will want to do is use array_column() on the $remove array to capture just the IDs from the array and then implode that new array and pass it to the query.

$to_remove = array_column($remove, 'id'); //assuming that id is the column you want
