Question

PHP是怎么返回json格式的数据

Answer 1

php 输出JSON格式,使用json_encode函数即可

例如:

<?php
header('Content-type: text/json');
$fruits = array (
    "fruits"  => array("a" => "orange", "b" => "banana", "c" => "apple"),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "holes"   => array("first", 5 => "second", "third")
);
echo json_encode($fruits);
?>

得到结果:

{"fruits":{"a":"orange","b":"banana","c":"apple"},"numbers":[1,2,3,4,5,6],"holes":{"0":"first","5":"second","6":"third"}}

Answer 2

最常用的是将一个数组组织成json格式

$arr = array("err"=>0,"errMsg"=>"success","data"=>array("a"=>"b","c"=>1));
echo json_encode($arr);

返回json类似：

{"error":0,"errMsg":"success","data":{"a":"b","c":1}}
