How to set local IP in PHP

When developing using PHP, we often need to use local IP to test and debug applications. Local IP can make it easier for us to conduct network debugging and application development. However, in the process of using PHP, sometimes we find that the PHP application cannot access the local IP, which requires us to set the local IP. This article will explain how to set a local IP in PHP.

1. What is local IP

Local IP usually refers to "127.0.0.1" or "localhost", which represents the network address of the local machine. When we develop using PHP, we can use the local IP to test and debug the application without deploying the application to a remote server. At the same time, we can also use local IP to access other local applications.

2. Why do you need to set the local IP

During the PHP development process, sometimes access to the local IP fails. This may be due to network configuration or PHP configuration issues. In order to be able to access the local IP normally, we need to configure PHP.

3. Set local IP

To set local IP, we need to modify the PHP configuration file. Under Windows systems, open the "php.ini" file; under Linux systems, you need to open the "/etc/php.ini" file. Modify the following two configuration items in the "php.ini" file:

; whether to allow the treatment of URLs (like http:// or ftp://) as files.
allow_url_fopen = On

; whether to allow include/require to open URLs (like http:// or ftp://) as files.
allow_url_include = On

Change the values ​​of these two configuration items to "On", save and restart PHP to set the local IP.

4. Frequently Asked Questions

1. How to determine whether the local IP is set successfully?

We can test whether the local IP is set successfully by opening the browser and entering "http://localhost/" or "http://127.0.0.1/". If the browser can successfully open the homepage of the web server, the setting is successful.

2. What should I do if the setting fails?

If setting the local IP fails, we can check the network configuration, try to re-modify the "php.ini" file, or seek help from the development community.

5. Summary

This article introduces how to set local IP in PHP. By modifying the PHP configuration file, local IP access and debugging can be easily achieved. During the development process, if you encounter the problem of failure to access the local IP, you can refer to the method in this article to make modifications.
