Why is it important to specify the server path when performing file operations in PHP?

Specifying the server path is important when performing file operations in PHP because it ensures that the script accesses the correct file location on the server. Without specifying the server path, the script may not be able to locate the file or may inadvertently access the wrong file, leading to errors or security vulnerabilities. By providing the server path, you can ensure that the file operations are performed accurately and securely. 

// Specify the server path to the file
$server_path = $_SERVER['DOCUMENT_ROOT'] . '/path/to/file.txt';

// Perform file operations using the server path
$file_content = file_get_contents($server_path);
echo $file_content;
