I have a JSON of the following format-
{
"FIRST": {
"group": {
"group_name": "first grp name",
"group_code": "FIRST"
},
"roles": [
{
"role_name": "Basic User",
"role_code": "FIRST_USER",
"role_description": "Basic user access",
"group_code": "FIRST"
}
]
},
"SECOND": {
"group": {
"group_name": "second grp name",
"group_code": "SECOND"
},
"roles": [
{
"role_name": "BASIC USER",
"role_code": "SECOND_USER",
"role_description": "SECOND User",
"group_code": "SECOND"
}
]
}
}
I need to remove the "roles" key and its value from both "FIRST" and "SECOND".
For this I do-
foreach($obj as $key => $val) {
unset($val['roles']);
$obj[$key] = $val;
}
And this gives me back the object just without the "roles". Is there a better way to do this without the loop?
My Answer:
{
"name": "John",
"age": 30,
"city": "New York"
}_
I want to remove the "age" key from this JSON object without using a loop in PHP. Here's how you can achieve this:
php
$json = '{
"name": "John",
"age": 30,
"city": "New York"
}';
$data = json_decode($json, true);
unset($data['age']);
$newJson = json_encode($data);
echo $newJson;
This code will output the following JSON object:
json
{
"name": "John",
"city": "New York"
}
