$a = '{"status":"3","message":"","errCode":"0","data":[{"time":"2014-12-12 20:37","context":"到达：湖南湘潭公司 已收件"},{"time":"2014-12-12 21:31","context":"到达：湖南湘潭公司 发往：福建厦门分拨中心"},{"time":"2014-12-13 02:24","context":"到达：湖南长沙分拨中心"},{"time":"2014-12-17 20:02","context":"到达：福建厦门公司国贸分部 发往：福建厦门公司国贸分部"},{"time":"2014-12-17 20:33","context":"到达：福建厦门公司国贸分部 由 图片 签收"}],"html":"","mailNo":"1201519497579","expTextName":"韵达快递","expSpellName":"yunda","update":"1420006818","cache":"0","ord":"ASC","tel":"021-39207888"}';
$b = json_decode($a);
$status = $b->status;
....
$message = '';
foreach($b->data as $v){
$message .= $v->time.' '.$v->context."\r\n";
}$str = your JSON
$obj = json_decode($str);
//Here status, message, errCode are equal to $obj ->status $obj -> message $obj ->errCode
//There is also tel which is also the outer layer
foreach ($obj->data as $data) {
//This will loop 4 times each time Both have $obj ->time $obj ->context
$jsonString = '....your json....';
$result = json_decode($jsonString, true);
$dataCount = count($result['data']);
if ($dataCount > 0) {
for ($i = 0; $i < $dataCount; $i++) {
// 这里处理每一条物流状态
}
}for ($i = 0; $i < $dataCount; $i++) {
// 这里处理每一条物流状态
}
这个for里面要怎么写才能调用time 跟context这2个内容 呢<?php
header('Content-type:application/json;charset=utf-8');
$json='{
"id": "1",
"name": "姓名",
"show": "内容",
"mp3_path": "目录"
}';
echo $json;
?><!DOCTYPE html>
<html lang="zh-cn">
<head>
<meta charset="utf-8">

var html="";
$.ajax({
type: "get",
url: "test01.php",
success: function (data)
{
//for in遍历php返回的json数据
for(var k in data)
{
//用模板字符串将key value,拼接到html字符串中。
html+=`<li>${k} :${data[k]}</li>`
}
$("#p1 ul").html(html);
},
error:function () {
alert("1111");
}
});
</script>
</body>
</html>3. Note: php files and html files should be located in the same directory, otherwise there will be cross-domain problems.
4. I placed these two files in the htdocs directory under xampp.
5. Open the file and you can see the output as follows.
