针对初学PHP者的疑难问答

apache conf session windows

初学

  1.问:为什么出现“APACHE.EXE: cannot determine local host name.”?
  答:

  由于Windows版本的Apache默认情况下不指定ServerName,所以运行时会出错。

  解决的办法是修改Apache安装目录下的conf目录下的httpd.conf:
- 搜索ServerName
- 去掉前面的#号
- 把ServerName后面的值换成你自己的设置,如localhost之类的
- 保存,重新启动Apache
  2.问:PHP代码中函数前面的@是什么意思?
  答:

  @的作用是忽略调用该函数时产生的错误信息。

  问3:为什么出现“APACHE.EXE: cannot determine local host name.”?

  答3:由于Windows版本的Apache默认情况下不指定ServerName,所以运行时会出错。

  解决的办法是修改Apache安装目录下的conf目录下的httpd.conf:
  - 搜索ServerName
  - 去掉前面的#号
  - 把ServerName后面的值换成你自己的设置,如localhost之类的
  - 保存,重新启动Apache
----------------------------------------------------------------------
  问4:为什么在WINDOWS下使用PHP4的SESSION功能老是报路径出错?
  答4:

  可能是PHP4.0在WINDOWS下的一个BUG。解决办法是把保存SESSION的路径设为当前路径(只有这样,才不会包错)。

  方法是修改php.ini,把session.save_path的值设为./

Four ways to implement multithreading in C language Four ways to implement multithreading in C language Apr 03, 2025 pm 03:00 PM

Multithreading in the language can greatly improve program efficiency. There are four main ways to implement multithreading in C language: Create independent processes: Create multiple independently running processes, each process has its own memory space. Pseudo-multithreading: Create multiple execution streams in a process that share the same memory space and execute alternately. Multi-threaded library: Use multi-threaded libraries such as pthreads to create and manage threads, providing rich thread operation functions. Coroutine: A lightweight multi-threaded implementation that divides tasks into small subtasks and executes them in turn.

Is Debian Strings compatible with multiple browsers Is Debian Strings compatible with multiple browsers Apr 02, 2025 am 08:30 AM

"DebianStrings" is not a standard term, and its specific meaning is still unclear. This article cannot directly comment on its browser compatibility. However, if "DebianStrings" refers to a web application running on a Debian system, its browser compatibility depends on the technical architecture of the application itself. Most modern web applications are committed to cross-browser compatibility. This relies on following web standards and using well-compatible front-end technologies (such as HTML, CSS, JavaScript) and back-end technologies (such as PHP, Python, Node.js, etc.). To ensure that the application is compatible with multiple browsers, developers often need to conduct cross-browser testing and use responsiveness

What are the key information in the Debian logs that cannot be ignored What are the key information in the Debian logs that cannot be ignored Apr 02, 2025 am 08:12 AM

The log files of the Debian system are valuable resources for system administrators and developers to diagnose problems and monitor the operating status of the system. This article will focus on some key log information that cannot be ignored. Core system logs (usually located in /var/log/syslog or /var/log/messages) These logs record the core activities of the system, including: system startup and shutdown events: log kernel version, hardware detection results, etc., to help track startup failures or shutdown exceptions. Hardware failure alerts: such as disk errors, memory problems, etc., to promptly detect potential hardware problems. Service status changes: Record the service start, stop and restart events to facilitate monitoring of the service's health. User login/logout history:
