How can hash generation, fopen, and unlink functions be effectively utilized in PHP for creating and deleting files dynamically?

To dynamically create and delete files in PHP, you can generate a unique hash for the file name, use fopen to create the file, and unlink to delete it when needed. This approach ensures that each file has a unique identifier and can be easily managed.

// Generate a unique hash for the file name
$hash = md5(uniqid());

// Create a new file using fopen
$file = fopen($hash . '.txt', 'w');
fwrite($file, 'Hello, World!');
fclose($file);

// Delete the file using unlink
unlink($hash . '.txt');
