Laravel / Eloquent : request that returns a count of id instances inside a table then stores it into a variable

I’m currently working on a project on laravel 8.
I have 3 tables : 1.customers 2.books 3.loans
I want to be able to make a request like $data=DB::table('emprunts')->where('customerid',$id->number)->first(); but where it would count the instances of loans with this customerid and return it into a variable.

I tried with

$limitemprunts = Emprunt::WhereIn('clientid',$search_text)->where('clientid',$search_text)->distinct()->get()->count();

but it gives me this error :

TypeError Argument 1 passed to
IlluminateDatabaseQueryBuilder::cleanBindings() must be of the type
array, string given, called in
C:xampphtdocs120120vendorlaravelframeworksrcIlluminateDatabaseQueryBuilder.php
on line 919

Method 1

You will need to convert the second parameter of whereIn into an array:

$limitemprunts = Emprunt::WhereIn('clientid',[$search_text])->distinct()->get()->count();

Method 2

As said in the comment, the answer was really simple : feed it an array
