我的 JSON 数据{ "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" } ] } ] } ]}我的PHPforeach($result->users as $ok) { foreach($ok->authority as $okey) { foreach($okey->mission as $okeyokey) { $test = $okeyokey->permission; echo $test; } } }怎么做这个？我想仅显示解析 json 权限{0} -> misson{0} 显示“权限”“添加”请帮助我。也许看看 ScreenShot >>>>> 我想要过滤器 {0}{1}{2} 并选择 0 -> 显示解析 json在此输入图像描述

这是你想要的？
<?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);

您对对象和数组感到困惑
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
}
}
}
}
}
确保您使用好的标签。虚拟占位符可能没问题，但它使跟踪错误变得非常困难。我假设您想检查他们是否拥有使用数据库、使用 PDO 的权限？
// 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.
您可以在 JSON 对象中包含数组，也可以在数组中包含 JSON 对象。您访问它们的方式有所不同。
