My (semi-educated) guess:

On edmullen.net, your php.ini file sets the error_reporting value to
E_ERROR, while on guitarsnotguns.org, the php.ini file sets the
error_reporting value to E_WARNING

E_ERROR settings will halt execution of the php script; if
filemtime($full_name) encounters a "file not found" error, the script
stops, and does not execute the subsequent printf() statements.

E_WARNING settings will not halt execution of the php script; if
filemtime($full_name) encounters a "file not found" error, the script
continues and tries execute the subsequent printf() statements.

Compare the php.ini settings (both explicit and implicit-default) from both
sites, especially the error_reporting and display_errors values, to see how
you've set PHP to handle errors.
