What is the purpose of using the PHP script to intercept a stream?

Intercepting a stream using a PHP script allows for manipulation of the data being transferred between a client and a server. This can be useful for tasks such as logging, modifying data on the fly, or implementing security measures. By intercepting the stream, the PHP script can act as a middleman, processing and potentially altering the data before passing it along to its destination. 

<?php
// Open a stream to the target URL
$stream = fopen('http://example.com/data', 'r');

// Read data from the stream
while (!feof($stream)) {
    $data = fgets($stream);

    // Manipulate the data as needed
    $modifiedData = strtoupper($data);

    // Output the modified data
    echo $modifiedData;
}

// Close the stream
fclose($stream);
?>
