PHP 原生的函数库支持解析 JSON 数据为 PHP 数组

json_decode($data,$boolean);

这其中 data 参数是 json 的文本数据，大概能实现这样的转换效果：

{
	"a": 1,
	"b": 2,
	"c": 3,
	"d": 4,
	"e": 5
}

[
    "one",
    "two",
    "three"
]

[
  {
    "attr": "string", 
    "attr_num": 1, 
    "boolean": true
  },
  {
    "attr": "string", 
    "attr_num": 1, 
    "boolean": true
  }
]

Array(
    'a'=>1,
    'b'=>2,
    'c'=>3,
    'd'=>4,
    'e'=>5
)

Array(
    '1'=>'one',
    '2'=>'two',
    '3'=>'three'
)

Array(
  [
    'attr' => 'string',
    'attr_num' => 1,
    'boolean' => true,
  ],
  [
    'attr' => 'string',
    'attr_num' => 1,
    'boolean' => true,
  ],
)

大概写个例子

$data=json_decode($json,true);
echo $data[0][attr];//echo 'string';

读取并解析远程 json 文件

//require CURL
function GetCurl($url){
    $curl = curl_init();
    curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($curl,CURLOPT_URL, $url);
    curl_setopt($curl,CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    $resp = curl_exec($curl);
    curl_close($curl);
    return $resp;
}
//get and parse data
$resp = GetCurl($data);
$resp = json_decode($resp,true);
