What are the common Apache operations in PHP programming?

In PHP programming, Apache is an important web server. When using PHP, you need to perform some common operations on it. These operations include the following points:

1. Start and stop the Apache server

The command to start the Apache server is: /etc/init.d/httpd start. If Apache is already running, you can use the command /etc/init.d/httpd restart to restart Apache.

The command to stop the Apache server is: /etc/init.d/httpd stop.

2. Configuring the Apache server

The configuration file of Apache is httpd.conf, which can be edited using the vim or nano editor to modify the settings in the configuration file. Some common configuration options include:

• Listening port: the default is port 80, the port number can be modified by modifying the Listen command;
• Virtual host: can be added by modifying the VirtualHost command , delete or modify the virtual host;
• Directory index: you can set the default file name by modifying the DirectoryIndex command (such as setting index.php as the default file);
• URL rewriting: you can modify it RewriteRule to rewrite the URL.

3. Configuring PHP

There are two ways to configure PHP scripts: one is to configure it in the httpd.conf file, and the other is to use . htaccess file to configure.

The way to configure in the httpd.conf file is to add the following code at the end of the file:

# 添加 PHP 模块
LoadModule php7_module modules/libphp7.so

# 解析 PHP 文件
AddHandler php7-script .php

# PHP 文件的 MIME 类型
AddType text/html .php

The way to configure using the .htaccess file is as follows:

# 开启 PHP 模块
AddHandler php7-script .php

# PHP 文件的 MIME 类型
AddType text/html .php

4. Configuration file upload

Sometimes you need to upload files, such as uploading pictures, videos, etc. To do this, we need to configure it in the Apache configuration file to upload the relevant files. For example, we can add the following code to the httpd.conf file:

# 设置上传限制
LimitRequestBody 10240000

# 对 POST 请求进行过滤
<IfModule mod_security.c>
  SecFilterEngine Off
  SecFilterScanPOST Off
</IfModule>

These are common Apache operations in PHP programming, and they are all to facilitate our development using PHP.
