如何使用php查找已安装的linux发行版？

Question

有没有办法找出哪个版本的Ubuntu安装了php？

在我会用的控制台上

cat /etc/lsb-release 

例如：

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

Answer 1

这将收集大量有用的数据：

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;
    $r["SERVER_SOFTWARE"]=@$_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
    /**

        's': Operating system name. eg. FreeBSD.
        'n': Host name. eg. localhost.example.com.
        'r': Release name. eg. 5.1.2-RELEASE.
        'v': Version information. Varies a lot between operating systems.
        'm': Machine type. eg. i386.
    */
    $r["kernel_release_name"]=php_uname('r');
    $r["os_name"]=php_uname('s');
    $r["uname_version_info"]=php_uname('v');
    $r["machine_type"]=php_uname('m');
    $r["php_uname"]=php_uname();

    if(stristr($r["uname_version_info"],"Ubuntu")){

        foreach($distribution as $distribution=>$name_kernel){

Answer 2

您可以解析/etc/lsb-发布信息。

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

Answer 3

$_SERVER[]可以帮上忙。

在我的mac上

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

我建议阅读/etc/lsb-版本中的文件。
