Sharing is caring. For this situations there are following command line methods to provide some data to be downloaded from everywhere.
On the most common linux systems is python preinstalled or is a part of the core system,
so the next two python-examples should work like a charm.

PHP Warning: PHP Startup: apc.shm_size now uses M/G suffixes, please update your ini files
Solution is pretty simple change in your php.ini
from:
1 | apc.shm_size=512 |
to
1 | apc.shm_size=512M |
You may need to specify “M” for Megabyte (MB) or “G” for Gigabyte(GB) to solve this issue.
PHP reveals its presence on the server in a variety of ways: It may send an HTTP header (X-Powered-By: PHP), or append its name and version to Apache’s signature. In addition, there are easter egg URLs that return the PHP logo or some PHP authors, one of them is:
http://www.host.com/index.php?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
Obviously there is no reason to let end users know about the server’s PHP version. Luckily, there is a switch in php.ini that will disable all of the above:
1 | expose_php = Off |
In order to do this, you need to do some sysdmin job:). I am going to specifically focus on Apache and PHP because I’m more of a LAMP user. If you use ASP on Microsofts IIS, I can’t help you (but hey!, Google is there to save your sunny day! :P)
Find your php.ini file in my case,
1 | vim /etc/php5/apache2/php.ini |
Look for the line that says: “expose_php On“
Change it to:
1 | expose_php Off |
Now our PHP is very silent
Note by PHP developer:
; Decides whether PHP may expose the fact that it is installed on the server
; (e.g. by adding its signature to the Web server header). It is no security
; threat in any way, but it makes it possible to determine whether you use PHP
; on your server or not.
