In what ways can PHP scripts be optimized for efficient file management on a server?

PHP scripts can be optimized for efficient file management on a server by minimizing the number of file operations, using appropriate file handling functions, and caching file data when possible. Additionally, using relative paths instead of absolute paths can improve portability and performance.

// Example of optimizing file management in PHP by using relative paths and minimizing file operations
$filename = 'data.txt';
$data = 'Hello, World!';

// Writing data to a file using relative path
file_put_contents($filename, $data);

// Reading data from a file using relative path
$file_contents = file_get_contents($filename);

echo $file_contents;
