I have thousands log files in a few directories in my system. Mostly I need to know just number of these files in directory. I fear that this attitude:

$files = count(scandir("logs")) - 2;

Is not very effective (memory, filesystem). I am considering some global counter (incremented after file is added), unless there is some other effective way?


$files = count(glob("logs/*",GLOB_NOSORT));

The fastest way to count the number of files in a directory (including , The simplest way: find <dir> -type f | wc -l. Slightly faster, perhaps: find <dir> -type f -printf '\n' | wc -l. But what I posted is a way of keeping track of changing number of file in a directory. for eg: while copying file from one location to another the number of file keeps changes. with the method I poster one can keep track of that.


Try to call system listing of files:

$files = exec('ls logs | wc -l');

Quick way to count files in large folder, One way to use find and count: find . -type f | wc -l. Count the number of subset of files in a directory hi I am trying to write a script to count the number of files, with slightly different subset name, in a directory for example, in directory /data, there are a subset of files that are name as follow /data/data_1_(1to however many).txt /data/data_2_(1 to however many).txt


Maybe with opendir/readdir?

<?php
$i = 0;
if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))
        if ($file != "." && $file != "..")
            ++$i;
    closedir($handle);
}
?>

How to count the files in a folder using PowerShell, CMD, or File , Read this tutorial to find out exactly how many files and/or folders are stored inside a folder. I will count all the files in a large network share (27.7 GB : 71 694 files and 8821 folders ). Important : in this test there are no long paths, access denied, etc. I will write another article about how to deal with exceptions. First, I just confirm that all these commands return the same result before measuring that.


I am also considering this "unary counter" solution: After each file is added, run this command

file_put_contents("counter_myDir","1",FILE_APPEND);

Then I would have some few kB more in each directory (there are just a few dirs, it is ok) and the reading seems to be very effective and portable, too:

$files = filesize("counter_myDir");

Can you please compare this to other solutions suggested here? I really need to know the number of files as effectively as possible.

Getting a list of 2 Million files in directories FAST! How?, I don't care about file sizes or any properties of the file/directory, I just want a recursive list of files names and directory names super fast! answers on cheers, but in powershell ls is an alias to Get-childitem $RemainingFolders = @() } until ($FoldersLeft.count -eq 0) $ListofFiles |out-file c:\temp\test4.txt }. Highlight all of the files, you can do this a number of ways; one method is to click on the first file or folder then press and hold Shift and click on the last file/folder. Another is to simultaneously press the Ctrl + A keys. Right click on the first file/folder and select Rename.


These are my totals when scanning around 30 folders, with ~5000 files each. Can't find a faster way than scandir except caching results (in memcached or something).

echo count(scandir('logs/'))-2; // 0.140 sec

echo system('find "logs/ | wc -l'); // 0.300 sec

echo system('ls -l logs/ | wc -l'); // 1.200 sec

echo count(glob('logs/*',GLOB_NOSORT)); // 1.800 sec
