PHP 5.6字符串数组到变量数组

我有这根绳子

$str = '[{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null}]'

我想把它变成一个变量数组

我在网上搜索过类似的情况，但什么也没找到。 只有简单的字符串，如

“some，test，string”

等

知道我该怎么做吗？

使用json_decode（）函数再次转换字符串数组

此字符串是json编码的对象。使用json_decode将此字符串解析为json对象。之后，您可以在循环中迭代并打印所有对象/数组：

$str = '[{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null},{"parousia":null,"proforikos":null,"test":null,"ergasias":null,"telikos":null}]';
$json = json_decode($str);

foreach($json as $obj) {
    var_dump((array)$obj);
}

“[{”parousia:“krishnsa”，“proforikos”：null，“test”：null，“ergasias”：null，“telikos”：n

ull]}`

$output = json_decode($str, true);
echo $output[0]["parousia"];

这根绳子是一根绳子。你希望输出的最终代码是什么？你能为我的错误提供样本吗
