How to access array values in laravel - php

Question

This method i am using for storing currentTime in database using ajax call and its working
public function saveTime(Request $request, $lession_id){
$user = Auth::user();
if($user === null){
return response()->json(['message' => 'User not authenticated', 404]);
}
$video = \App\Lession::where('id',$lession_id)->first();
$lesson_id = $request->lession_id;
$progress = $request->time;
//save them somewhere
$watch_history = $user->watch_history;
$watch_history_array = array();
if ($watch_history == '') {
array_push($watch_history_array, array('lession_id' => $lesson_id, 'progress' => $progress));
} else {
$founder = false;
$watch_history_array = json_decode($watch_history, true);
for ($i = 0; $i < count($watch_history_array); $i++) {
$watch_history_for_each_lesson = $watch_history_array[$i];
if ($watch_history_for_each_lesson['lession_id'] == $lesson_id) {
$watch_history_for_each_lesson['progress'] = $progress;
$watch_history_array[$i]['progress'] = $progress;
$founder = true;
}
}
if (!$founder) {
array_push($watch_history_array, array('lession_id' => $lesson_id, 'progress' => $progress));
}
}
$data['watch_history'] = json_encode($watch_history_array);
$check = User::where('id',$user->id)->update(['watch_history' => $watch_history_array]);
return response()->json(['message' => 'Time saved', 200]);//send http response as json back to the ajax call
}
But when I use this another method to get the time back for playback it's getting the array inside an array
public function getTime(Request $request, $lession_id){
$user = Auth::user();
if($user === null){
return response()->json(['message' => 'User not authenticated', 403]);
}
$user_video = User::where('id',$user->id)->first();
$array = $user_video->watch_history;
foreach ($array as $key => $value) {
echo $check;
}
}
My current Output in a database is as follows
[{"lession_id":"157","progress":"71.449464"},{"lession_id":"156","progress":"92.113123"}]
So help me to get the values out of that for each lession id
