有沒有什麼辦法知道一個PHP腳本是否在cli模式下運行？

Question

......或者相反，有沒有什麼辦法可以知道一個php腳本是否在web服務器中運行？

Answer 1

http://www.php.net/manual/en/function.php-sapi-name.php

function is_cli() 
{ 
    return php_sapi_name() === 'cli'; 
} 

Answer 2

通常，在CLI模式下運行時，超全球變體和$argc將被設置，並且許多$_SERVER（例如請求方法）的典型內容將不可用。另外，將會設置預定義的控制檯流，例如STDIN,STDOUT和STDERR。

Answer 3

你可以檢查$ _SERVER變量...如：

$_SERVER['SERVER_ADDR'] 

如果不通過網絡服務器執行這將是空的。

Answer 4

我寫了一個小PHP腳本，只包含此行：

print_r($_SERVER); 

當我在命令行中執行它，這是我輸出的一部分：

rascher@eggs:~$ php test.php 
Array 
(
    [TERM] => xterm 
    [SHELL] => /bin/bash 
    [SSH_CLIENT] => 192.168.1.104 57547 22

在網絡服務器上運行同樣的東西給了我這個：

Array 
(
    [HTTP_HOST] => xxxx.com 
    [HTTP_USER_AGENT] => Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.6) Gecko/2009020911 Ubuntu/8.10 (intrepid) Firefox/3.0.6

    [HTTP_ACCEPT_ENCODING] => gzip,deflate 
    [HTTP_ACCEPT_CHARSET] => ISO-8859-1,utf-8;q=0.7,*;q=0.7 
    [HTTP_KEEP_ALIVE] => 300 
    [HTTP_CONNECTION] => keep-alive 
    [HTTP_PRAGMA] => no-cache 
    [HTTP_CACHE_CONTROL] => no-cache 
    [PATH] => /sbin:/usr/sbin:/bin:/usr/bin 
    [SERVER_SIGNATURE] => <address>Apache/2.2.6 (Fedora) Server at xxxx.com Port 80</address> 

    [SERVER_SOFTWARE] => Apache/2.2.6 (Fedora) 
    [SERVER_NAME] => xxxx.com 
    [SERVER_ADDR] => 208.109.29.70 
    [SERVER_PORT] => 80 
    [REMOTE_ADDR] => 69.134.191.151 
    [DOCUMENT_ROOT] => /xxxx/httpdocs 
    [SERVER_ADMIN] => jpg@gfhome.com 
    [SCRIPT_FILENAME] => /xxxx/args.php 
    [REMOTE_PORT] => 52187 
    [GATEWAY_INTERFACE] => CGI/1.1 
    [SERVER_PROTOCOL] => HTTP/1.1 
    [REQUEST_METHOD] => GET 
    [QUERY_STRING] => 
    [REQUEST_URI] => /args.php 
    [SCRIPT_NAME] => /args.php 
    [PHP_SELF] => /args.php 
    [REQUEST_TIME] => 1236102678 
) 

注意的是這些增值經銷商，這最終可能是最有用的：

[argv] => Array 
    (
     [0] => test.php 
    ) 

[argc] => 1
