Accessing email from MySQL db to be use for sending email - php

Question

I have a problem with my message notification using email.Why is that it generates an error inside the foreach.
The error is this part "$all_ngo" Undefined variable: all_ngo.
$pend = AddRequest::where('ship_id','=',$ship_id)->get();
$all_ngo = [];
foreach ($pend as $id) {
array_push($all_ngo, $id->ngo_id);
}
$orga_email = Auth::User()->orgainfo->orga_email;
$staffName = Auth::User()->orgainfo->inchargelname.' '. Auth::User()->orgainfo->inchargefname;
$name = $scholars->scholar_fname.' '.$scholars->scholar_mname.' '.$scholars->scholar_lname;
$input = array(
'name' => $staffName,
'email' => $orga_email,
'msgs' => 'asd' .' '. $name.'. '.'Hoping for your favorable response. Thank you!'
);
Mail::send('emails.mailMessage', $input, function($message){
$message->from('Somename#gmail.com');
foreach ($all_ngo as $id3) {<-------Undefined variable: all_ngo
$user = User::find($id3);
$ngo_email2 = $user->ngo_email;
$message->to($ngo_email2)->subject('Request For Sponsorship');
}
});

Answer 1

Because $all_ngo is out of scope. You can solve this by adding a global $all_ngo; into the function:
Mail::send('emails.mailMessage', $input, function($message) {
global $all_ngo;
$message->from('Somename#gmail.com');
foreach ($all_ngo as $id3) {<-------Undefined variable: all_ngo
$user = User::find($id3);
$ngo_email2 = $user->ngo_email;
$message->to($ngo_email2)->subject('Request For Sponsorship');
}
});
or allow the anonymous function to access the variable:
Mail::send('emails.mailMessage', $input, function($message) use ($all_ngo) {
$message->from('Somename#gmail.com');
foreach ($all_ngo as $id3) {<-------Undefined variable: all_ngo
$user = User::find($id3);
$ngo_email2 = $user->ngo_email;
$message->to($ngo_email2)->subject('Request For Sponsorship');
}
});
