[英]How to go through each element in JSON array in PHP
I want to echo out each element of an object of a JSON array like this: 我想要回显出JSON数组的对象的每个元素,如下所示:
{"request_list":[{"id":"1","name":"yunus","surname":"smsk","phone_number":"05350601922","blood_type":"0","unit_of_blood":"0","date":null},{"id":"3","name":"yunus","surname":"smsk","phone_number":"05350601922","blood_type":"0","unit_of_blood":"0","date":null}]}
But i cannot do it.I tried somethinglikethis: 但我不能这样做。我尝试过这样的事情:
$object = json_decode($json, true);
$request_list = $object->request_list;
foreach($request_list as $r){
echo $r->name;
echo $r->blood_type;
echo $r->phone_number;
}
But I got an error like: 但我得到一个错误:
Invalid argument supplied for foreach()
为foreach()提供的参数无效
As you have mark return as array true in json_decode
. 因为你在
json_decode
标记返回为数组true。 So, try below code. 所以,试试下面的代码。
$object = json_decode($json, true);
$request_list = $object['request_list'];
foreach($request_list as $r){
echo $r['name'];
echo $r['blood_type'];
echo $r['phone_number'];
}
Use this 用这个
$object = json_decode($json, true);
$request_list = $object['request_list'];
foreach($request_list as $r){
echo $r['name'];
echo $r['blood_type'];
echo $r['phone_number'];
}
try 尝试
$json = '{"request_list":[{"id":"1","name":"yunus","surname":"smsk","phone_number":"05350601922","blood_type":"0","unit_of_blood":"0","date":null},{"id":"3","name":"yunus","surname":"smsk","phone_number":"05350601922","blood_type":"0","unit_of_blood":"0","date":null}]}';
$data = json_decode($json );
$request = $data->request_list;
foreach($request as $request_data){
echo $request_data->id;
echo $request_data->name;
echo $request_data->surname;
}
