Validate array if already exists in mysql php laravel - php

Question

Currently I have set of array.
and
I can easily insert these data to my database using Laravel without doing any validations
here's the sample array
CODE:
$excel1 = Importer::make('Excel');
$excel1->hasHeader(true);
$excel1->load($savePath.$fileName);
$excel1->setSheet(2);
$collection1 = $excel1->getCollection();
$arr1 = json_decode($collection1,true);
foreach ($arr1 as $row1) {
$insert_data1[] = array(
'projCode' => $projCode,
'emp_id' => $row1['company_id'],
'type' => 'EMP',
'deleted' => 0,
'by_id' => auth()->user()->id,
'updated_by' => auth()->user()->name,
'created_at' => now(),
'updated_at' => now(),
);
}
dd($insert_data1);
OUTPUT:
and I'm using this code to insert these data to my table
DB::table('tbl_emp_proj')->insert($insert_data1);
and this works fine but the problem is,
I'm trying to validate if emp_id exists or not in my users table
Here's my users table
The value of emp_id from array should check if it already exists in my users using company_id field from users. How can I validate it if $insert_data1 is an array and should be check if it exists on database?
UPDATE
currently i have this validator and I tried to add up the $Insert_data1 but gives me undefined var for $insert_data1.
$validator = Validator::make(
[
'file' => $request->file,
'extension' => strtolower($request->file->getClientOriginalExtension()),
],
[
'file' => 'required|max:5000',
'extension' => 'required|in:,csv,xlsx,xls',
],
$insert_data1,
[
'*.emp_id' => "required|exists:users,company_id",
]
);

You can use Laravel Validator to validate any arrays as if its a request input.
use Illuminate\Support\Facades\Validator;
$validator = Validator::make(
$insert_data1,
[
'*.emp_id' => "required|integer|exists:users,company_id",
]
);
EDIT:
You can receive error messages and error items with the validator APIs.
$failed = $validator->fails(); //boolean
$errors = $validator->errors();
$validated = $validator->validated();
$invalid = $validator->invalid();
