编辑:

要使其完整，请查看 print_r($_SERVER) 给我的内容，从命令行执行:

Array
(
    [TERM_PROGRAM] => Apple_Terminal
    [TERM] => xterm-color
    [SHELL] => /bin/bash
    [TMPDIR] => /var/folders/Lb/LbowO2ALEX4JTK2MXxLGd++++TI/-Tmp-/
    [TERM_PROGRAM_VERSION] => 272
    [USER] => felix
    [COMMAND_MODE] => unix2003
    [__CF_USER_TEXT_ENCODING] => 0x1F5:0:0
    [PATH] =>/Library/Frameworks/Python.framework/Versions/Current/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/usr/X11/bin
    [PWD] => /Users/felix/Desktop
    [LANG] => de_DE.UTF-8
    [SHLVL] => 1
    [HOME] => /Users/felix
    [LOGNAME] => felix
    [DISPLAY] => /tmp/launch-XIM6c8/:0
    [_] => ./test_php2
    [OLDPWD] => /Users/felix
    [PHP_SELF] => ./test_php2
    [SCRIPT_NAME] => ./test_php2
    [SCRIPT_FILENAME] => ./test_php2
    [PATH_TRANSLATED] => ./test_php2
    [DOCUMENT_ROOT] => 
    [REQUEST_TIME] => 1260658268
    [argv] => Array
      (
        [0] => ./test_php2
      )

    [argc] => 1
    )

我希望我没有暴露相关的安全信息；)

Windows 兼容性

请注意，$_SERVER['HOME'] 在 Windows 上不可用。相反，该变量被拆分为 $_SERVER['HOMEDRIVE'] 和 $_SERVER['HOMEPATH']。
