foreach not looping all data - php

Question

my first query that gets all rows that contain both the user who requested friendship ( authenticated user id ) and inbound friendship ( inbound user id ). This works if I echo $rowsget, it echos the correct rows, the problem I'm having is that it will only loop through up to two usernames, once I take away the ability for it to loop through the profiles own username it will only loop through one row then stop, I have tried what some people have said to do but it now says this error message when I try to load the profile page, "Object of class Illuminate\Support\Collection could not be converted to int" Here is the code, any help is appreciated, I have been stuck on this for hours now.
Query
$rowsget = DB::table('friends')->where(function(Builder $query) use($uid) {
$query->where('requesteeid', $uid)
->orWhere('inboundid', $uid);
})
->where('approved', true)
->get();
$rowfetchfriend = [];
if(count($rowsget) > 0){
foreach($rowsget as $get) {
$getrequestee = $get->requesteeid;
$getinbound = $get->inboundid;
$rowfetchfriend += DB::table('users')->where('id', $getrequestee)-
>orWhere('id', $getinbound)->get(['id', 'avatar', 'username']);
}
Loop through usernames
foreach($rowfetchfriend as $loop) {
if($loop->id != $uid) { //make sure own user isnt displayed
echo $loop->username; // echo all usernames that are
}
}
}

Answer 1

Use this method (or the push() method) when adding to an array:
Instead of this:
$rowfetchfriend += DB::table('users')->where('id', $getrequestee)->orWhere('id', $getinbound)->get(['id', 'avatar', 'username']);
Try this:
$rowfetchfriend[] = DB::table('users')->where('id', $getrequestee)->get(['id', 'avatar', 'username']);
$rowfetchfriend[] = DB::table('users')->where('id', $getinbound)->get(['id', 'avatar', 'username']);
The class and its methods are listed here:

You can use "push" method of laravel collection.
try this :
$rowfetchfriend = [];
if(count($rowsget) > 0) {
foreach($rowsget as $get) {
$getrequestee = $get->requesteeid;
$getinbound = $get->inboundid;
$temp = DB::table('users')->where('id', $getrequestee)->orWhere('id', $getinbound)->get(['id', 'avatar', 'username']);
array_push($rowfetchfriend, $temp->toArray());
}
}
and Loop through usernames :
for ($i=0; $i < count($rowfetchfriend); $i++) {
if($rowfetchfriend[$i][0]->id != $uid) { //make sure own user isnt displayed
echo $rowfetchfriend[$i][0]->username; // echo all usernames that are
}
}
I tested it and work correctly.
