URL 的 Base64_encode

Question

Is there a base64_encode function that is URL safe in PHP?

It also needs to be decodable obviously.

Answer 1

urlencode(base64_encode($var));

Answer 2

尝试这个。

Answer 3

No. There isn't one built-in.

You can simply do this,

$encoded = strtr(base64_encode($data), '+/=', '-_.');
$data = base64_decode(strtr($encoded, '-_.', '+/='));
