What are the potential benefits of using temporary files in PHP scripts?

Using temporary files in PHP scripts can help improve performance by reducing memory usage, especially when dealing with large amounts of data. Temporary files can also help with data persistence, allowing data to be stored and accessed across multiple script executions. Additionally, temporary files can be useful for handling file uploads, as they provide a secure and efficient way to process and store uploaded files. 

// Create a temporary file
$tempFile = tempnam(sys_get_temp_dir(), 'prefix');

// Write data to the temporary file
file_put_contents($tempFile, $data);

// Read data from the temporary file
$data = file_get_contents($tempFile);

// Delete the temporary file
unlink($tempFile);
