解决方案

您需要使用 将 json 响应转换为 php 数组json_decode。

片段

$json = '{
"ver":1,
"inputs":[
  {
     "sequence":4294967295,
     "witness":"",
     "prev_out":{
        "spent":true,
        "tx_index":372805487,
        "type":0,
        "addr":"3AFgA1pHKrk4jFHwzUL1CKgZvXyFSWZfgD",

}';
$arr = json_decode($json, true); // you can use $arr direct as json hierarchy

//or convert to one-dimensional array
$result = [];
array_walk_recursive($arr, function ($item, $key) use (&$result){
    $result[$key] = $item;
});
print_r($result);

输出

Array

    [ver] => 1
    [sequence] => 4294967295
    [witness] => 
    [spent] => 
    [tx_index] => 377146538

现场演示

请注意：您可以$arr用作 json 层次结构，也可以将所有键和值转换为一维数组。

警告：重复的键将被覆盖
