Undefined Variable in Laravel Command - php

Question

I have added into a Laravel command mail::send to send an email to all users who meet the criteria. Whenever I run the first part of my foreach statement but gives me an [ErrorException] Undefined Variable: member whenever it gets to the emailing. My fire function code is below.
public function fire()
{
$members = Member::where('expire', '=', Carbon::now()->today());
$this->info('We found ' . $members->count() . ' expiring today (' . Carbon::now()->today() . ')!');
foreach ($members->get() as $member) {
$member->active = "0";
$member->save();
$this->comment($member->first_name . ' has been updated.'); //This is the last line which runs
Mail::send('emails.member.membership_expired', array('name'=>$member->first_name. ' ' . $member->last_name), function($message){
$message->to($member->email, $member->first_name . ' ' . $member->last_name)->subject('Your Membership has Expired');
});
}
}

Answer 1

With Mail::send you use a closure (also called anonymous function). To use local variables inside the closure you have to pass them in with use. Like that:
Mail::send('emails.member.membership_expired',
array('name'=>$member->first_name. ' ' . $member->last_name),
function($message) use ($member){
$message->to($member->email, $member->first_name . ' ' . $member->last_name)->subject('Your Membership has Expired');
}
);
