Servers list does not stick when using opcode caching extensions

[GoogleCodeExporter]

The configuration of phpmemcacheadmin is stored in *.php file. Thus, when you 
use opcode cache (APC, ZendOptimizer+, etc.) with 'timestamp revalidation' 
setting turned off, you will see that the configuration is not updated and the 
phpmemcacheadmin does not work at all.

Possible solution: change extension of config file from *.php to, for instance, 
*.json, or read the config directly from a file instead of including/requiring 
it via PHP.
