{"rows":1,"code":"hklhc","info":"开奖API（测试接口2-3分钟随机显示最新一期）","data":[{"expect":"2023026","opencode":"04,01,14,07,37,31,11","opentime":"2023-03-09 21:35:00"}]} 我要用php提取data的数值，要怎么写

您可以使用以下PHP代码提取"data"数组中的值：

$json_data = '{"rows":1,"code":"hklhc","info":"开奖API（测试接口2-3分钟随机显示最新一期）","data":[{"expect":"2023026","opencode":"04,01,14,07,37,31,11","opentime":"2023-03-09 21:35:00"}]}';

$data = json_decode($json_data, true)['data'][0];

$expect = $data['expect'];
$opencode = $data['opencode'];
$opentime = $data['opentime'];

echo "expect: " . $expect . "<br>";
echo "opencode: " . $opencode . "<br>";
echo "opentime: " . $opentime . "<br>";

运行该代码，将输出以下结果：

expect: 2023026
opencode: 04,01,14,07,37,31,11
opentime: 2023-03-09 21:35:00

其中，$expect、$opencode和$opentime分别是"data"数组中对应的值。
