php 获取本地IP代码

Sure! Here is a step-by-step guide on how to get the local IP address using PHP:

1. First, you need to create a PHP file. You can name it get_local_ip.php or any other name you prefer.

2. Open the PHP file in a text editor or an integrated development environment (IDE).

3. Start by writing the PHP opening tag <?php to indicate the beginning of PHP code.

4. To get the local IP address, you can use the $_SERVER superglobal variable. Specifically, you can access the REMOTE_ADDR key to retrieve the IP address of the client making the request.

php
$ip = $_SERVER['REMOTE_ADDR'];

The $ip variable will now contain the IP address of the client.

1. To display the IP address, you can use the echo statement. For example:

php
echo \"Your IP address is: \" . $ip;

This will output a message along with the IP address.

1. Save the PHP file.

2. To test the code, you need to run a local web server or upload the file to a web server. If you're running a local server, you can access the PHP file through your web browser by navigating to http://localhost/get_local_ip.php or the appropriate URL.

3. When you access the PHP file, you should see the message along with the IP address displayed on the page.

Here are two examples to illustrate the usage:

Example 1:

<?php
$ip = $_SERVER['REMOTE_ADDR'];
echo \"Your IP address is: \" . $ip;
?>

Output:

Your IP address is: 192.168.0.1

Example 2:

<?php
$ip = $_SERVER['REMOTE_ADDR'];
echo \"Your IP address is: \" . $ip;
?>

Output:

Your IP address is: 10.0.0.1

Remember, the IP address displayed will depend on the network configuration and the client making the request.
