从手册我得到的信息：
mode is a single character that defines what information is returned: 'a': This is the default. Contains all modes in the sequence "snrvm". '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. 所以我创build了一个函数
function interpret_php_uname(){ $release_info["os_name"] = php_uname('s'); $release_info["uname_version_info"] = php_uname('v'); $release_info["machine_type"] = php_uname('m'); $release_info["php_uname"] = php_uname(); return $release_info; }
有没有办法从我的uname在Ubuntu上获得更多有用的信息？

特别是从我的机器上的“uname_version_info”部分找出发行版 （“Ubuntu 13.10”）。
#23-Ubuntu SMP Mon Dec 9 18:17:04 UTC 2013
<?php function interpret_php_uname(){ $release_info["os_name"] = php_uname('s'); $release_info["uname_version_info"] = php_uname('v'); $release_info["machine_type"] = php_uname('m'); $release_info["kernel"] = php_uname('r'); $release_info["php_uname"] = php_uname(); $distribution["4.10"]=array("Warty Warthog", "2.6.8"); $distribution["5.04"]=array("Hoary Hedgehog", "2.6.10"); $distribution["5.10"]=array("Breezy Badger", "2.6.12"); $distribution["6.06"]=array("Dapper Drake", "2.6.15"); $distribution["6.10"]=array("Edgy Eft", "2.6.17"); $distribution["7.04"]=array("Feisty Fawn", "2.6.20"); $distribution["7.10"]=array("Gutsy Gibbon", "2.6.22"); $distribution["8.04"]=array("Hardy Heron", "2.6.24"); $distribution["8.10"]=array("Intrepid Ibex", "2.6.27"); $distribution["9.04"]=array("Jaunty Jackalope", "2.6.28"); $distribution["9.10"]=array("Karmic Koala", "2.6.31"); $distribution["10.04"]=array("Lucid Lynx", "2.6.32"); $distribution["10.10"]=array("Maverick Meerkat", "2.6.35"); $distribution["11.04"]=array("Natty Narwhal", "2.6.38"); $distribution["11.10"]=array("Oneiric Ocelot", "3.0"); $distribution["12.04"]=array("Precise Pangolin", "3.2"); $distribution["12.10"]=array("Quantal Quetzal", "3.5"); $distribution["13.04"]=array("Raring Ringtail", "3.8"); $distribution["13.10"]=array("Saucy Salamander", "3.11"); $distribution["14.04"]=array("Trusty Tahr", "3.13"); foreach($distribution as $distribution=>$name_kernel){ list($name,$kernel)=$name_kernel; if(version_compare($release_info["kernel"],$kernel,'>=')) { $release_info["ubuntu_distribution"]=$distribution; $release_info["ubuntu_distribution_name"]=$name; } } return $release_info; } $release_info=interpret_php_uname(); var_export($release_info);
将打印例如：
array ( 'os_name' => 'Linux', 'uname_version_info' => '#23-Ubuntu SMP Mon Dec 9 18:17:04 UTC 2013', 'machine_type' => 'x86_64', 'kernel' => '3.11.0-15-generic', 'php_uname' => 'Linux geisterhaufen 3.11.0-15-generic #23-Ubuntu SMP Mon Dec 9 18:17:04 UTC 2013 x86_64', 'ubuntu_distribution' => '13.10', 'ubuntu_distribution_name' => 'Saucy Salamander', )
不，那里没有。 uname函数只报告正在运行的内核的信息 – 它不包含任何正在使用的Linux分发信息。 内核版本有时可能会附带包含分发的名称，但情况并非总是如此。
根据正在使用的Linux发行版，信息可能以/etc中的各种文件提供，包括但不限于：
/etc/os-release /etc/debian_version /etc/lsb-release /etc/redhat-release
