Ubuntu上的PHP从命令行加载MSSQL扩展，但在通过Apache运行时不加载

Question

I've been searching and trying for quite a while to find an answer, so will finally ask here.

I have a UBUNTU install from Turnkey LINUX, PHP Ver 5.6.23. I have compiled and enabled mssql.so as I require to connect to a MSSQL server.

My simple connect PHP script is so:

$server = 'rslocal';

$connect = mssql_connect($server, 'sqluser', 'sqlpassword');

if (!$connect) {
    echo 'can not connect';
}

I can run the above PHP script from the command line and it is successful.
I can also run the FreeTDS tsql utility and connect and query the server from the command line

When I run it from the browser through Apache, it tells me Fatal error: Call to undefined function mssql_connect() ...

I have checked that php --ini (cli) and phpinfo() (browser) both report the same ini file in use.

I am not running SELinux so the setbool commands are not relevant here, however the problems stated by others where SELinux WAS the issue are exactly the same as mine, so perhaps this is a place to start.

My feeling is that it is a security policy or something stopping the extension from loading any function that wants to communicate with an outside server, but I am stuck.

Any help would be appreciated.

I found the "answer". On this distro, Ubuntu 14.x, the command

sudo apachectl restart

doesn't seem to be enough to reload php. The php.ini change, specifically adding extension=mssql.so had not been not applied when run through apache. This raises the question how to "hard" restart Apache so php.ini changes take, but that's a different question. I only noticed that it worked after a reboot.
