读取 curl php 结果

Question

I'm doing a curl and getting the JSON result as:

$data = json_decode($result, true);
var_dump($data);
$data = $data["data"];
echo $data;

However, the echo of $data is "{". If I do a var_dump before assigning again the variable I see:

string(727796) "{"data":["base64_image1", "base64_image2",... ]}"

Why am I not able to access the data list? I just want to do a foreach over this list, but I cannot.

Answer 1

输出是 json，所以再次尝试 json_decode()
