php将项添加到foreach循环之外的数组中

Question

What I'm trying to do is loop through an array of items and add each of them to my db. After they're added to the db, the 'Add' class' function should return the status and message of each item. I'm trying to add each of these statuses and messages to an outcome array that's outside my foreach loop and then when the loop completes I'm trying to print the outcome array but I keep getting this error: Trying to get property of non-object in <b>pathToTheLoop\ScheduleController.php</b> on line <b>38</b><br /> . The line which is specified points to where I'm trying to add the stuff to my outcome array.

Anyway, here's my code:

$returned = array();
foreach ($dates as $date) {
  $startStr = $date . " " . $start;
  $startDate = DateTime::createFromFormat('d/m/Y H:i:s', $startStr);
  $endStr = $date . " " . $end;
  $endDate = DateTime::createFromFormat('d/m/Y H:i:s', $endStr);

  $sdl = new Schedule($startDate, $endDate, null);
  $outcome = $sdl->createSlot();
  $returned['status'] = $outcome->status;
  $returned['message'] = $outcome->message;
}
print json_encode($returned);

Note that I've tried populating my array with the method above, as well as with the following method:

$returned[] = array(
  $status => $outcome->status,
  $message => $outcome->message
);

I'm not including the code for the Schedule class because I'm fairly certain that it works because stuff I send to add to the db actually gets added and also because if I replace the part where I'm trying to populate the array with a print // the outcomes it actually prints it.

Edit: When I do var_dump($outcome); instead of trying to add the outcomes to $returned I get this:

array(2) {
  ["status"]=>
  string(7) "success"
  ["message"]=>
  string(62) "New slot added from 2016-10-10 09:00:01 to 2016-10-10 10:00:00"
}
array(2) {
  ["status"]=>
  string(7) "success"
  ["message"]=>
  string(62) "New slot added from 2016-10-17 09:00:01 to 2016-10-17 10:00:00"
}
array(2) {
  ["status"]=>
  string(7) "success"
  ["message"]=>
  string(62) "New slot added from 2016-10-24 09:00:01 to 2016-10-24 10:00:00"
}
array(2) {
  ["status"]=>
  string(7) "success"
  ["message"]=>
  string(62) "New slot added from 2016-10-31 09:00:01 to 2016-10-31 10:00:00"
}

It appears that the value of $outcome is an array rather than an object so you could try casting the result as an object and that should allow you to use the object notation to access the values.

  $outcome = (object)$sdl->createSlot();
  $returned['status'] = $outcome->status;
  $returned['message'] = $outcome->message;

or, alternatively use the array notation

  $outcome = $sdl->createSlot();
  $returned['status'] = $outcome['status'];
  $returned['message'] = $outcome['message'];
