Laravel Divided Query Overwrites Previous Variable - php

Question

What I am trying to achieve is to create a query and use it with multiple endings:
For example
$query = User::where('is_admin', true);
if ($query->where('badge', 'red')->exists())
{
//do something
}
if ($query->where('badge', 'green')->exists())
{
//do something
}
$query->get();
$query->first();
With this, the $query variable gets overwritten every time the query is finished therefore it is not possible to re-use $query;
The current solution I have is utilizing clone
$query = User::where('is_admin', true);
$query1 = clone $query;
if ($query1->where('badge', 'red')->exists())
{
//do something
}
$query2 = clone $query
if ($query2->where('badge', 'green')->exists())
{
//do something
}
$query3 = clone $query;
$query3->get();
$query4 = clone $query;
$query4->first();
The example is used just to get the point across, not a real
life scenario.
I guess it works and does what I want, just does not feel like a laravel way of doing something, quite verbose and it gets worse with more complicated logic.
The goal is to re-use the same variable without overwriting it every time I finalize the query.
Does anybody have a better solution to this?
Is there a way to somehow break the reactivity of the $query variable?
Thanks

An elegant option is to make use of Laravel Local Query Scopes.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
/**
* Scope a query to only include administrators.
*
* #param \Illuminate\Database\Eloquent\Builder $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeAdmins($query)
{
return $query->where('is_admin', true);
}
}
Now, to utilize the newly created local scope:
if (User::admins()->where('badge', 'red')->exists())
{
//do something
}
if (User::admins()->where('badge', 'green')->exists())
{
//do something
}

For starters, $query doesn't sound like a good name for fetching Users that are admins.
so, let's quickly change it so it's more clear for us to read and think
$user_admins = User::where('is_admin', true);
if ($user_admins->where('badge', 'red')->exists())
{
//do something
}
if ($user_admins->where('badge', 'green')->exists())
{
//do something
}
okay, so we grabbed admins, let's iterate through them with a foreach loop
$user_admins = User::where('is_admin', true);
foreach($user_admins as $admin) {
if ($admin->badge == 'green') {
// do something
} else if ($admin->badge == 'red') {
// do something else
}
}
now, whenever you change the $admin variable inside the loop, it will change that individual admin.
also query is the "question" eloquent is "asking" the database (for example: "SELECT * FROM users WHERE is_admin=true"; so query does not not refer to the result.
note you could also use a switch statement if you have a lot of logic, it would look like this:
$user_admins = User::where('is_admin', true);
foreach($user_admins as $admin) {
switch($admin->badge) {
case 'green:
// do something
break;
case 'red:
// do something else
break;
case 'ltblue:
case 'blue:
// do same things for ltblue and blue
break;
default: break;
}
