是执行 PHP 指令的那个程序的权限。

比如使用 Apache httpd 的 PHP 模块时,(如果没有用 suexec 之类的配置)是 apache 配置文件里指定的用户(比如 www-data)。

比如使用 nginx 通过 FastCGI 传给 php-fpm 时,是 php-fpm 配置文件里指定的用户。

是对应的web服务器执行的
nginx 查看nginx.conf里面的user指令
apache 查看apache2.conf里面的User指令,可能倒入了envvars里面的变量
export APACHE_RUN_USER=www-data

或者查看phpinfo里面
Configuration apache2handler
的user/group

除了通过对应配置文件查找之外,一种更方便的方法是打印$_SERVER

通常$_SERVER['USER']就是用户名

最简单的办法,用
ps aux | grep nginx
或者 ps aux | grep php-fpm
再或者 ps aux | grep httpd
查看进程的用户名,那个就是了^_^

The Compatibility of IIS and PHP: A Deep Dive The Compatibility of IIS and PHP: A Deep Dive Apr 22, 2025 am 12:01 AM

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How to understand DMA operations in C? How to understand DMA operations in C? Apr 28, 2025 pm 10:09 PM

DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.
