Is this what you are looking for?
<?php
$jsonData = '{
"users": [
{
"userid": 1,
"username": "Admin",
"usermail": "admin#admin.com",
"authority": [
{
"authorityid": 1,
"authoritytext": "Admin",
"mission": [
{
"permission": "add"
},
{
"permission": "delete"
},
{
"permission": "move"
}
]
},
{
"authorityid": 1,
"authoritytext": "Super Admin",
"mission": [
{
"permission": "no add"
},
{
"permission": "no delete"
},
{
"permission": "only moderate"
}
]
}
]
}
]
}';
$data = json_decode($jsonData);
echo($data->users[0]->authority[0]->mission[0]->permission);

Answer 2

You are getting objects and arrays confused
foreach($result->users as $currentUser){
$auths = $currentUser->authority;
foreach($auths as $currentAuth){
foreach($currentAuth->mission as $permission){
foreach($permission as $positionLabel => $permissionValue){
if($permissionValue == "add"){
// code here
}
}
}
}
}
Make sure you are using good labels. Dummy placeholders can be fine, but it makes tracking bugs really hard. I assume you want to check if they hold permission using a database, using PDO?
// array
$arr = ["this", "is", "an", "array"];
echo $arr[0] // prints out the word this.
$json = { "attribute": "value"}
echo $json->attribute // prints out the word value.
You can have arrays in JSON objects, and JSON Objects in arrays. How you access them are different.
