apc.rfc1867无法通过php.ini启用

I am trying to turn on using the below in my php.ini file

apc.rfc1867 = on

I'm doing this to allow me to build a progress bar for file uploads.

I am hosted on a Godaddy shared server and am not able to edit the php.ini directly, so am creating a new one and adding the above code to it. This doesn't seem to be having an effect though on activating this option. i've also used

<?php
echo 'apc.enabled = ' . ini_get('apc.enabled') . "
";
echo 'apc.rfc1867 = ' . ini_get('apc.rfc1867') . "
";
?>

and was initially returned with

apc.enabled = 1
apc.rfc1867 = 0

but now i've randomly been returned with

apc.enabled = 
apc.rfc1867 = 

and through checking phpinfo() i can no longer see any of the apc options.

does this mean APC is now disabled? why would this happen?

For GoaDaddy shared use php.ini not php5.ini in your root level folder. apc.rfc1867 = 1
