How can the use of shell commands like wget be integrated into PHP scripts for remote file operations?

To integrate shell commands like wget into PHP scripts for remote file operations, you can use the `exec()` function in PHP to execute the shell command. This allows you to download files from a remote server using wget directly from your PHP script. 

<?php
$url = 'http://www.example.com/file.txt';
$outputFile = 'downloaded_file.txt';

// Use wget to download the file
exec("wget $url -O $outputFile");

echo "File downloaded successfully!";
?>
