PHP urlsafeB64Decode()

with padding

function base64url_decode($input) { 
    return base64_decode(strtr($input, '-_', '+/').str_repeat("=",-strlen($input) & 3));
} 
echo base64url_decode('SGVsbG8gV29ybGQ='); # Hello World

without padding ★

function urlsafeB64Decode($input)
{
    $remainder = strlen($input) % 4;
    if ($remainder) {
        $padlen = 4 - $remainder;
        $input .= str_repeat('=', $padlen);
    }
    return base64_decode(strtr($input, '-_', '+/'));
}
echo urlsafeB64Decode('SGVsbG8gV29ybGQ'); # Hello World

function urlsafeB64Decode($input)
{
    return base64_decode(strtr($input, '-_', '+/'));
