Why mcrypt_get_iv_size does not work in PHP Version 5.3.10-1ubuntu3?

[wow]

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,

[wow]

Any one has any idea, why the following code doesn't show any thing and disappear? Where is mcrypt installed with ubuntu? Thanks,

$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);

Below are modules installed, is mcrypt included?

core mod_log_config mod_logio prefork http_core mod_so mod_alias mod_auth_basic mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host mod_authz_user mod_autoindex mod_cgi mod_deflate mod_dir mod_env mod_mime mod_negotiation mod_php5 mod_reqtimeout mod_setenvif mod_status

It's fixed now: the mcrypt module is not installed. The weird thing is php and ubuntu doesn't have any message for the problem. Just vanish in the air. Thanks,
