--TEST--
Test base64_decode() function : basic functionality - strict vs non-strict with non-base64 chars.
--FILE--

--EXPECTF--
Decode 'hello world!':
string(12) "hello world!"
string(12) "hello world!"
string(12) "hello world!"

Whitespace does not affect base64_decode, even with $strict===true:
string(12) "hello world!"
string(12) "hello world!"
string(12) "hello world!"

Other chars outside the base64 alphabet are ignored when $strict===false, but cause failure with $strict===true:
string(12) "hello world!"
string(12) "hello world!"
bool(false)
Done
