什么是确定命令行与PHP脚本的http执行的规范方法? [英] What is the canonical way to determine commandline vs. http execution of a PHP script?
问题描述
我有一个PHP脚本,需要确定是否已通过命令行或通过HTTP执行,主要用于输出格式化目的。这是什么规范的方式?我认为这是检查 SERVER ['argc']
,但事实证明,这是填充,即使使用'Apache 2.0处理程序'服务器API。
I have a PHP script that needs to determine if it's been executed via the command-line or via HTTP, primarily for output-formatting purposes. What's the canonical way of doing this? I had thought it was to inspect SERVER['argc']
, but it turns out this is populated, even when using the 'Apache 2.0 Handler' server API.
推荐答案
使用 php_sapi_name()
函数。
if (php_sapi_name() == "cli") {
// In cli-mode
} else {
// Not in cli-mode
}
以下是文档中的一些相关注释:
Here are some relevant notes from the docs:
php_sapi_name - 返回Web服务器和PHP之间的接口类型
php_sapi_name — Returns the type of interface between web server and PHP
虽然不完全,但可能的返回值包括aolserver,apache ,apache2filter,apache2handler,caudium,cgi(直到PHP 5.3),cgi-fcgi,cli,cli-server,continuity,embed,isapi,litespeed,milter,nsapi,phttpd,pi3web,roxen,thttpd,tux和webjames。 / p>
Although not exhaustive, the possible return values include aolserver, apache, apache2filter, apache2handler, caudium, cgi (until PHP 5.3), cgi-fcgi, cli, cli-server, continuity, embed, isapi, litespeed, milter, nsapi, phttpd, pi3web, roxen, thttpd, tux, and webjames.
在PHP> = 4.2.0中,还有一个预定义的常量, PHP_SAPI
,其值与 php_sapi_name()
相同。
In PHP >= 4.2.0, there is also a predefined constant, PHP_SAPI
, that has the same value as php_sapi_name()
.
