Hi there,

The following code runs well in Windows 7 PHP Version 5.3.2, but not in PHP Version 5.3.10-1ubuntu3. It does not show any error message. It's Just vanished in the air and nothing. It's very confused. What's the problem?

$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);

Thanks,
