如何找出用php安装的linux发行版？

有没有办法找出哪个版本的Ubuntu安装与PHP？如何找出用php安装的linux发行版？

在控制台上我会用

cat /etc/lsb-release

，并会得到例如：

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

所以，你想要写一个PHP代码片段，报告它的运行机器的操作系统的详细信息？我有没有得到那个权利？ –

这是完美的 – rubo77

另请参阅http://stackoverflow.com/questions/1482260/how-to-get-the-os-on-which-php-is-running。我不确定它是否会向你显示确切的Ubuntu版本，但你可以根据内核版本（'php_uname（'r'）;'）来判断它。 – Mike

这将收集了很多有用的数据：

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; 
    $r["SERVER_SOFTWARE"][email protected]$_SERVER["SERVER_SOFTWARE"]; 
    $r["osx_system_arch"][email protected]$_SERVER["_system_arch"];// Mac-specific for ex.=> x86_64 
    $r["osx_system_version"][email protected]$_SERVER["_system_version"];// Mac-specific for ex.=> 10.9

这将是更好，甚至更好[解释php_uname的输出]（http://stackoverflow.com/questions/21129737/how-do-i-interpret-the-output-of-php-uname） – rubo77

现在它确实.... – rubo77

的$ _ SERVER []可以提供帮助。

我的Mac上我有

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

我会推荐阅读在/ etc/LSB释放的文件。

你可以找到更多信息here

这两个文件都必须是Mac特有的，因为这两种文件对于Ubuntu服务器都不存在，并且它们都不在列出的链接中。 – Mike

$ _SERVER是一个PHP数组，而不是Mac特有的。 –

是的，但Linux上的$ _SERVER数组不包含''_system_arch“'或'_system_version”' – Mike

你可以分析/ etc/LSB释放的信息。

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

只要没有open_basedir限制，就比'php_uname'更好。 – Mike
