I am using php 5.3.3 on Cent OS 6.
I find that in my web application that a call to ini_get("memory_limit")
returns an empty string.
When I try and reproduce this error in a command line script
I cannot reproduce this behavior.
Does anyone here have any experience with this unexpected behavior?
If so, what causes this to happen? Seemingly it only occurs when the
code is executed via Apache?

Check you actually have a memory limit set:
$ grep memory_limit /etc/php5/apache2/php.ini
memory_limit = 128M

Can't say as I've seen it. What's your entire code? And what does
phpinfo() show?
Even if you don't set a memory limit, PHP should have a default (128M).

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.

Thank you (and everyone else on this thread!) for the advice.
Turns out that a bit of third party code is calling ini_set() and
screwing everything up. I just didn't realize it when I made my post.
This whole business of calling ini_set() is pretty evil!
