base64_decode问题

Question

If i decode base64 encoded bitmap, i get back nothing. Where as i should get some binary data.

Suppose $data contains base64 encoded bitmap.

$decoded = base64_decode($data);

if i echo $decoded it prints nothing even its length is '0'. Shouldnt it contain something after decoding?

Also can you decode base64 encoded binary data in php?

Answer 1

我做错了，即使api表示加密的数据也没有加密。
