How can I combine all the files I have in a directory?
I want them to be all copied in a document to be called "combined.txt"

cat $(ls -t) > combined.txt

That's a Linux command. Wrap it in PHP and you're set.

Yes but the first one has certain criteria, while this one is any file in the directory

Then just remove the criteria - make it *.*

So for the first sample
<?php
$output = 'combined.txt';
$files = glob("*.*");
unlink($output);
foreach($files as $f) {
    file_put_contents($output, file_get_contents($f), FILE_APPEND);
}

Open in new window

Second option adapted from (Ray's Solution)
$input = 'path/to/input';
$output = 'path/to/combine.txt';
$iterator = new FilesystemIterator($input, FilesystemIterator::SKIP_DOTS + FilesystemIterator::CURRENT_AS_PATHNAME);
unlink($output);
foreach ($iterator as $key => $filepath)
{
    file_put_contents($output, file_get_contents($filepath), FILE_APPEND);
}

Open in new window


EDIT:
The Second solution is about 4x faster than the first.

Corrected code - there were errors in the post above
$iterator = new FilesystemIterator($input, FilesystemIterator::SKIP_DOTS + FilesystemIterator::CURRENT_AS_PATHNAME);
@unlink($output);
foreach ($iterator as $key => $filepath)
{
  file_put_contents($output, file_get_contents($filepath), FILE_APPEND);
}

And in case there are folders in the input directory
$iterator = new FilesystemIterator($input, FilesystemIterator::SKIP_DOTS + FilesystemIterator::CURRENT_AS_PATHNAME);
@unlink($output);
foreach ($iterator as $key => $filepath)
{
  if (!is_dir($filepath)) {
    file_put_contents($output, file_get_contents($filepath), FILE_APPEND);
  }
}
