Do you get an empty string or false?
var_dump(ini_get("memory_limit"));

If you actually get an false value, then you managed to enter some 
invisible characters into the string and those the value can't be found.

Empty string and false looks the same if you are doing

echo ini_get("memory_limit");

you using the same script or you written another one? If later than you 
have not got the invisible characters and those it "works" as you expect 
in cli while it seem to work trough Apache.
