What is the best way to automatically copy log files from multiple subdirectories into a single directory using PHP?

To automatically copy log files from multiple subdirectories into a single directory using PHP, you can use the RecursiveDirectoryIterator and RecursiveIteratorIterator classes to iterate through all subdirectories and files. You can then check if the file is a log file using pathinfo() function and copy it to the destination directory using copy() function. 

$sourceDir = '/path/to/source/directory';
$destinationDir = '/path/to/destination/directory';

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($sourceDir));

foreach ($iterator as $file) {
    if ($file->isFile() && pathinfo($file, PATHINFO_EXTENSION) == 'log') {
        $destinationFile = $destinationDir . '/' . $file->getFilename();
        copy($file, $destinationFile);
    }
}
