PHP Linux Script Programming Practice: Implementing Network Requests and Processing

Overview:
In the modern Internet era, network requests and processing are becoming more and more important. By using PHP and Linux script programming, we can implement various network request operations, such as HTTP requests, FTP transfers, etc., and process the returned data to achieve various functions and requirements. This article will introduce how to use PHP and Linux script programming to implement network requests and processing, and provide specific code examples.

1. Implement HTTP request
   HTTP request is the most common network request method, and we can use PHP's curl extension to achieve it. Here is a simple example to send a GET request and get the returned data:

2. Implementing FTP transfer
   FTP transfer is a common file transfer method, we can use PHP's built-in FTP function to achieve. The following is an example to upload files to an FTP server:

3. Implementing data processing
   After obtaining the data returned by the network request, we may need to process and parse it. The following is an example to parse JSON data:

"; echo "Age: " . $data['age'] . "
"; echo "City: " . $data['city'] . "
"; ?>

Summary:
Through the above example, we can see that network requests and processing can be easily implemented using PHP and Linux script programming. We can use PHP's curl extension to send HTTP requests, use PHP's FTP function to implement FTP transmission, and use PHP's JSON parsing function to process the returned data. These functions provide convenience for us to realize various network needs, and we can expand and modify them according to specific needs.

Note: The above code is only an example. In actual application, it needs to be modified and adjusted according to the specific situation to ensure security and stability.
