In what scenarios would using pipes or temporary files be more appropriate than creating files in-memory in PHP?

Using pipes or temporary files may be more appropriate than creating files in-memory in PHP when dealing with large amounts of data that may exceed memory limits, when needing to pass data between different processes or programs, or when needing to store data temporarily without cluttering the filesystem. 

// Example of using temporary files to store data instead of in-memory

$tempFile = tmpfile();
fwrite($tempFile, "Hello, this is some data that needs to be stored temporarily.");
rewind($tempFile);

// Read data from temporary file
echo fread($tempFile, filesize(stream_get_meta_data($tempFile)['uri']));

// Close and delete temporary file
fclose($tempFile);
