Does php set the external network access address?

PHP is a popular web programming language commonly used to develop dynamic websites and web applications. After you develop your application, you may want to publish it to the Internet so that others can access it. So, how to set the external network access address in PHP?

In PHP, you can set the external network access address by configuring the Web server. Specifically, the following are the steps to set the external network access address on the Apache server:

1. Determine the IP address of the Web server

First, you need to know the IP of the Web server address. You can find the IP address of the web server at the console or by using the command ipconfig (Windows) or ifconfig (UNIX/Linux).

2. Configuring the Apache server

In the Apache server, you need to edit the httpd.conf configuration file. This file can be opened using a text editor. Some operating systems can use the command vi /etc/httpd/conf/httpd.conf to open this file.

Add the following code at the end of the file:

Listen 80

ServerName yourservername
DocumentRoot "/path/to/your/document/ root"

AllowOverride All

where , yourservername is the name of the server, you can fill it in at will; /path/to/your/document/root is the root directory of the web application, that is, the URL of the application accessed through the browser. Make sure this directory has the correct permissions for read and execute operations.

3. Configure virtual host

In the Apache server, you can use virtual hosts to host multiple domain names, each domain name has its own root directory. You can configure a virtual host by following these steps:

Add the following code to the httpd.conf configuration file:

ServerName yourdomain.com
ServerAlias ​​www.yourdomain.com
DocumentRoot /path/to/your/domain/root
ErrorLog /path/to/log/file/error_log
CustomLog /path/to/log/file/access_log common

Where, yourdomain.com is the domain name; /path/to/your/domain/root is the root directory of the Web application; /path/to/log/file/error_log and /path/to/log/file/access_log is the location of the error log and access log.

4. Restart the Apache server

After completing the above steps, you need to restart the Apache server for the changes to take effect. You can use the command apachectl restart (UNIX/Linux) or service apache2 restart (Ubuntu) to restart the server.

Summary

In PHP, setting the external network access address needs to be configured in the web server. Specifically, if you use an Apache server, you can edit the httpd.conf configuration file to add a virtual host, and restart the server. This will ensure that the web application is accessible through the external network so that others can access it.
