如何从php中的数据字符串中提取一系列变量？

以下数据块与其他html数据一起由网页生成

"search":{"searchResults":{"results":[

{"id":"123","name":"ABC","rating":{"average":0,"count":2,"__typename":"Rating"},"category":"AAA/Cars","__typename":"ProductQuery"},

{"id":"456","name":"DEF","rating":{"average":5,"count":8,"__typename":"Rating"},"category":"BBB/Bikes","__typename":"ProductQuery"}

{"id": //and so on//
"}

]}}

---

如何从这个字符串中提取多个变量，如“id”、“rating”等数据，以便在另一个php页面上打印？

您可以使用

json\u decode

将json转换为数组，然后在数组中迭代

$json = '{
"search":
 {
 "searchResults":
 {
    "results":[
            {"id":"123","name":"ABC","rating":{"average":0,"count":2,"__typename":"Rating"},"category":"AAA/Cars","__typename":"ProductQuery"},
            {"id":"456","name":"DEF","rating":{"average":5,"count":8,"__typename":"Rating"},"category":"BBB/Bikes","__typename":"ProductQuery"}
    ]
  }
 }
}';
$jsonToArray = json_decode($json,true);
foreach($jsonToArray['search']['searchResults']['results'] as $v){
   echo $v['id'];
  print_r($v['rating']);echo '<br/>';
}

$json=”{
“搜索”：
{
“搜索结果”：
{
“结果”：[
{“id”：“123”，“name”：“ABC”，“rating”：{“average”：0，“count”：2，“\uuu typename”：“rating”}，“category”：“AAA/Cars”，“\uuu typename”：“ProductQuery”}，
{“id”：“456”，“name”：“DEF”，“rating”：{“average”：5，“count”：8，“rating”}，“category”：“BBB/Bikes”；“ProductQuery”}
]
}
}
}';
$JSONTORARY=json_decode（$json，true）；
foreach（$jsonToArray['search']['searchResults']['results']作为$v）{
echo$v['id']；
打印（$v[“评级]）；回显“
”；
}
