json parsing with php foreach
提问by Aryadika Setyaji
I was trying to parsing json file below from a link but I still can't figure it out about parsing and display it with foreach.
我试图从链接解析下面的 json 文件，但我仍然无法弄清楚解析并使用 foreach 显示它。
data: [
{
id: "1072",
nik: "013977",
status: "",
name: "RAKHMAT KUSNADI",
birthdate: "1983-10-21",
email: "[email protected]",
first_login: "0",
is_juri: "0",
what_juri: "",
categorized: "0",
back_stage: "0",
placement: [
{
rel_id: "1102",
employee_id: "1072",
department_id: "101",
dept: "Chip",
position_id: "1",
position: ""
}
],
profile_pics: "link"
},
{
id: "1069",
nik: "013377",
status: "",
name: "RENATA MARINGKA",
birthdate: "1987-05-20",
email: "",
first_login: "1",
is_juri: "0",
what_juri: "",
categorized: "0",
back_stage: "0",
placement: [
{
rel_id: "1099",
employee_id: "1069",
department_id: "101",
dept: "Chip",
position_id: "1",
position: ""
}
],
profile_pics: "link"
},
]
}
I want to display name and profile_pics where department id is 101.
我想显示部门 ID 为 101 的姓名和 profile_pics。

Reinventing the wheel, are we? Why not simply use:
重新发明轮子，是吗？为什么不简单地使用：
$jsonObj = json_decode($jsonString);//returns stdClass instance, just an object
$jsonArr = json_decode($jsonString, true);//converts object to associative array
Read more on json_decodehere... It's quite easy to use, really
在json_decode这里阅读更多......它非常易于使用，真的
If you decode the data to an array, you could loop through the data like so
如果将数据解码为数组，则可以像这样遍历数据
while($item = array_shift($jsonArr))
{
foreach ($item as $key => $value)
{
echo $key.' => '.$value."\n";
}
}
Or simply use any old for/foreachloop on an object, its a traversable object anyway (though it doesn't implement the Traversableinterface)
或者简单地在对象上使用任何旧的for/foreach循环，无论如何它都是一个可遍历的对象（尽管它没有实现Traversable接口）

Use json_decode
使用 json_decode
$arr = json_decode($jsonstring, true);
then use foreach loop
然后使用 foreach 循环
foreach($arr as $val) {
if($val['placement']['department_id'] == "101") {
//display what u want
}
}

First step is to convert to an array
第一步是转换为数组
$data = json_decode($json);
Once you've got the array, you can then loop through it and check the values
获得数组后，您可以遍历它并检查值
$keepers = array();
foreach ($data as $item) {
if ($item->placement->department_id == 101) {
$keepers[] = $item;
}
}

Probably something like:
大概是这样的：
$data = json_decode($your_json);
foreach($data as $object) {
echo 'This is the name: ' . $object->name . PHP_EOL ;
}
回答by Connor
$data = json_decode($json, true)
Then whatever info you want out you get out with the foreach loop
然后无论你想要什么信息，你都可以用 foreach 循环
foreach ($data->id as $id)
{
echo $id;
}
With that you can set any variable like $data->nik as $nikor whatever you want then echo them back
有了它，您可以设置任何变量，例如$data->nik as $nik或任何您想要的，然后回显它们

usr this
用这个
foreach ($data->id as $id)
{
echo $id;
}
