I have this JSON ["{\"clube\":[\"Flamengo\"]}"] , and when I run this code:
$clubes = '["{\"clube\":[\"Flamengo\"]}"]';
$clubes = json_decode($clubes, true);
array_push($clubes->clube, 'Santos');
return $clubes;
I have this error as a return
Attempt to modify property of non-object
I wanted to leave JSON like this ["{\"clube\":[\"Flamengo\", "Santos"]}"]
You have converted clubs to array and used object notation within array_push .
$str = '{ "clube":["Flamengo"] }';
$tempArray = json_decode($str, true);
array_push($tempArray['clube'], 'Santos');
print_r($tempArray);
The second parameter of the json_decode function defines whether json will be kept as objeto or converted to array , as you passed true then it was defined that it would be used as array , but in line:
array_push($clubes->clube, 'Santos');
You're using objeto notation instead of array :
array_push($clubes['clube'], 'Santos');
