Query Server for Apache version only

[Boofo]

Can someone please tell me why I get an undefined function error when running this code in the functions.php? I want to query the server for the Apache version without getting the long string you get using SERVER_SOFTWARE.

$apacheversion = apache_get_version();

apache_get_version() is only available in PHP version > 4.3.2, so this might be the cause.

Try this snippet:

$ar = split("[/ ]", getenv("SERVER_SOFTWARE"));
$apacheversion = $ar[1];

Thank you, sir. That worked great! ;)

The server I am on is running PHP v4.3.3. I'm not sure why that code I posted doesn't work. It should have. :surprised:

Is there also a way to get the version of UNIX or Linux (as my server has)?

Is apache running as a module or as CGI? As apache_get_version() only works if its run as a module.

[Boofo]

You got me on that one. I have no idea which way they have it set up. Apparently, it must be set up as CGI since the script gives me the unknown function error, right? :) Is one way really any better than the other?

Also, is there a way to pull the Linix version number out, too?

[NTLDR]

Apache as a module is the better method to use, take a look at the Server API part of phpinfo() at the very top and it should say Apache if your running it as a module.

For the Linux version info, provided you can run shell_exec() you can get the OS info with:

$info = shell_exec('uname');

There are various options to add to get different stuff:


Usage: uname [OPTION]...
Print certain system information. With no OPTION, same as -s.

-a, --all print all information
-m, --machine print the machine (hardware) type
-n, --nodename print the machine's network node hostname
-r, --release print the operating system release
-s, --sysname print the operating system name
-p, --processor print the host processor type
-v print the operating system version
--help display this help and exit
--version output version information and exit


The info will be returned in the $info variable. I'd advise against making this information publicly available though ;)

[Boofo]

Is there such a thing as this for the Linux version?

#1 SMP Mon Aug 18 14:34:09 EDT 2003

That's what it returns.

I only have this info displayed for Admins. It is not available to the other users. ;)

The Server API just says Apache.

[NTLDR]

If you mean the Linux Kernel version then uname -r is what you want.

I've just tired apache_get_version(); on my server and it seems to work correctly for me with the Server API as Apache (ie a module), however, I think what you get returned from that is the same as you'll get from getenv('SERVER_SOFTWARE'); as both return Apache for me as I've set it to not show any other details in httpd.conf.

[Boofo]

It must be running as CGI on my server then. That would explain why I get the error. The code KirbyDE posted above gave me just the version number of Apache and nothing else. That's all I needed as I already have the other info.

I tried the -r and this is what I got:

2.4.20-20.7smp

Does that look right to you? What does the smp stand for?

What is the exact code you used with this? apache_get_version();

[NTLDR]

Yes, that looks right ;) The SMP (symmetric multiprocessing) part means your kernel has been complied to support more than one CPU.

I just did:


<?php

echo apache_get_version();

?>


Which gave me the same result as what I see on my phpinfo() page for the SERVER_SOFTWARE variable.

This is what I get when I try to run it:

Fatal error: Call to undefined function: apache_get_version() in XXXXXXXXXX :(
