Where test.json is the json you uploaded, place it in a file named test.json and ensure its placed in the same directory.

test.json是您上传的json,将其放在名为test.json的文件中,并确保将其放在同一目录中。

<?php

$load = file_get_contents("test.json") or die("JSON load failed");    
$json_a = json_decode($load, true);
print $json_a['data']['order']['ip_address'] . "\n"; 

?>

Gives:

123.456.789.111

My answer reads the JSON from a file as were it dumped directly in your code, which indeed it could be, it would make the code less readable and your file more messy.

我的答案从文件中读取JSON,因为它直接在您的代码中转储,实际上它可能是,它会使代码更不易读,文件更麻烦。

If you dont want to place the file in the same directory, simply specify the full file path. E.g. file_get_contents("this/dir/here/test.json");

如果您不想将文件放在同一目录中,只需指定完整的文件路径即可。例如。的file_get_contents( “本/ DIR /位置/ test.json”);

You can read about how json_decode works here, its essential we pass it the true parameter to make our arrays associative.

你可以阅读json_decode如何在这里工作,它必不可少的我们传递真正的参数来使我们的数组关联。

You can extract your need array from JSON data. You can use a loop too to read all your data inside the order array.

您可以从JSON数据中提取您的need数组。您也可以使用循环来读取订单数组中的所有数据。

$array = json_decode($json, true);

$verbose = $array['data'];
$orderArray = $verbose['order'];

print_r($orderArray);

echo $orderArray['id'];
echo $orderArray['ip_address'];
