When developing with backend technologies like PHP,  a time comes when you need to use and manipulate JSON objects.  One of such manipulations is removing or deleting a JSON key.
There are several ways to do this, however, I find the below method preferable.







unset($json["key"]);




1

unset($json["key"]);





Note that for this method to work, you need to pass a true parameter to the second argument of the json_decode() method.  See the below sample:







$json = json_decode($json , true);
unset($json["key"]);




12

$json = json_decode($json , true);unset($json["key"]);





The second parameter simply tells the method to return an associative array instead of an object.
Hope this helps.
