Re: [PHP] Number of files in a dir
cope with readdir() or dir(). I always use one of these functions and I'm wondered if there are more efficient solution to do it ! - Original Message - From: Shaun Thornburgh [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, November 02, 2002 9:00 AM Subject: [PHP] Number of files in a dir How can i find out how many files exist in a dir? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Nothing to do with PHP and everything to do with the OS. FWIW 20K files in one directory on Linux is slow. -- Jason Wong - Gremlins Associates - www.gremlins.com.hk Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * /* Yow!

Tens of thousands can start to become a problem. Look at the distribution of your file names and come up with a hashing mechanism. For instance, if your filenames are numbers, create subdirectories 0/ 1/ 2/ 3/ 4/ etc., and place the files based on their final digit. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
