php 如何接json回傳並顯示？透過curl

Question

{
    "list": [
        {
            "sample-id": "111",
            "title": "你好",
            "sample": ""
        },
        {
            "sample-id": "222",
            "title": "我很好",
            "sample": ""
        },
        {
            "sample-id": "333",
            "title": "你呢",
            "sample": ""
        }
    ]
}

假設某個HTTP API給我這樣的東西
我要怎麼透過php印出 title 等等其他東西？

Answer 1

json_decode了解一下：对json格式的字符串进行编码。

Answer 2

通过curl请求，获取json数据，然后解析，假设给你的API是GET请求，简单示例如下

function doGet($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $data = curl_exec($ch);
    curl_close($ch);
    return json_decode($data, true);
}

$url  = 'http://xx.com/api/lists';
$data = doGet($url);
var_dump($data);
$list   = $data['list'];
$titles = array_column($list, 'title');
