从字符串更改为 PHP 数组

Question

我的数据库中有一个字符串，例如：

$arr = [{"detail":"33,putih","sku":"123","price":"21","stok":"5"},{"detail":"33,hitam","sku":"528","price":"75","stok":"5"},{"detail":"34,hitam","sku":"775","price":"49","stok":"5"}]

但我想将此字符串转换为数组，我尝试使用explode like：

$array = explode('{"', $arr);

我对结果以及如何获得它感到困惑， 但结果不像我想要的。我希望我只能得到 sku[0] 或 detail[0] 等等。

Answer 1

您可以在 PHP 中使用 json_decode() 方法将您的 JSON 字符串转换为 array：

$str_json = '[{"detail":"33,putih","sku":"123","price":"21","stok":"5"},{"detail":"33,hitam","sku":"528","price":"75","stok":"5"},{"detail":"34,hitam","sku":"775","price":"49","stok":"5"}]';

$arr = json_decode($str_json,true);

json_decode() 函数的第二个参数设置为true，这将产生一个关联数组。
