PHP on Centos can't exec("ping google.com"); but can exec("whoami");

This is on a Centos 6 machine with a pretty standard install.

I run 

exec("whoami");

and I get 

apache

I run 

exec("ping google.com");

and I get nothing at all. No result.

I run the exact same code on an Ubuntu machine and everything works.

Now, I don't necesarily need a solution to the problem (though that would be nice) but I can't even figure out how to go about debugging. Is there a way to log the raw output of the command? All I can get so far is a return value of "2" which is "other error."

There are a number of questions similar to this one on Stackexchange, but most of them have to do with file permissions, which shouldn't be an issue here.

Nevermind. It's SELinux. It's always SELinux. Now to figure out how to grant apache permission to use ping...
