Is there a way to find out which release of Ubuntu is installed with php?

on the console I would use

cat /etc/lsb-release

and would get for example:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=13.10
DISTRIB_CODENAME=saucy
DISTRIB_DESCRIPTION="Ubuntu 13.10"

  • So you want to write a PHP snippet that reports the OS details of the machine it's run on? Did I get that right? – Tieson T. Jan 15 '14 at 04:18

    See also http://stackoverflow.com/questions/1482260/how-to-get-the-os-on-which-php-is-running. I'm not sure if it would show you the exact Ubuntu release, but you could probably figure it out based on the kernel version (`php_uname('r');`). – Mike Jan 15 '14 at 04:19

You can parse /etc/lsb-release for info.

<?php
$release_info = parse_ini_file("/etc/lsb-release");
echo $release_info["DISTRIB_ID"];
echo $release_info["DISTRIB_RELEASE"];
echo $release_info["DISTRIB_DESCRIPTION"];
?>

  • That's way better than `php_uname` as long as there's no sort of open_basedir restrictions. – Mike Jan 15 '14 at 04:33

This would collect a lot of useful data:

function get_release_info(){
    if(!$r = @parse_ini_file("/etc/lsb-release")){
        if(!$r = @parse_ini_file("/etc/os-release")){
            $r = @parse_ini_file("/etc/redhat-release");
        }
    }
    /*for ex:
        $r["DISTRIB_ID"]=Ubuntu
        $r["DISTRIB_RELEASE"]=13.10
        $r["DISTRIB_CODENAME"]=saucy
        $r["DISTRIB_DESCRIPTION"]="Ubuntu 13.10"
    */
    $r["debian_version"]=trim(@file_get_contents("/etc/debian_version")); // for ex. "wheezy/sid"
    $r["PHP_OS"]=PHP_OS;
    $r["SERVER_SOFTWARE"]=@$_SERVER["SERVER_SOFTWARE"];
    $r["osx_system_arch"]=@$_SERVER["_system_arch"];// Mac-specific for ex.=> x86_64
    $r["osx_system_version"]=@$_SERVER["_system_version"];// Mac-specific for ex.=> 10.9
    /**

  • It would be nice to even better [interpret the output of php_uname](http://stackoverflow.com/questions/21129737/how-do-i-interpret-the-output-of-php-uname) – rubo77 Jan 15 '14 at 05:30

The $_SERVER[] can help.

On my mac I have

$_SERVER["_system_arch"] => x86_64
$_SERVER["_system_version"] => 10.9

I would recommend this to reading the file in /etc/lsb-release.
