note 79396 added to function.glob

After much testing I find that although glob() is much cleaner than opendir(), it is also much slower. I started by making a dir called "cache" in which I placed a single 65k html file filled with whitespace (just so I could have a large filesize without worrying about char output). Based on the code below <?php //Waste a little time to offset PHP's startup. for($i=0; $i<20; $i++) { print ' '; } $start_time = time()+microtime(true); ob_start(); for($x=0; $x < 20; $x++) { $dir = 'cache/'; if (is_dir($dir)) { if ($dh = opendir($dir)) { while (($file = readdir($dh)) !== false) { //Include the file include($file); //$value = rand(0, 10000) * 2345678; } closedir($dh); } } } ob_end_clean(); print ((time()+microtime(true)) - $start_time). ' (opendir time)<br />'; $start_time = time()+microtime(true); ob_start(); for($x=0; $x < 20; $x++) { //Include the function files foreach (glob("cache/*.html") as $file) { //Include the file include($file); //$value = rand(0, 10000) * 2345678; } } ob_end_clean(); print ((time()+microtime(true)) - $start_time). ' (glob time)<br />'; ?> The result was: 0.0069890022277832 (opendir time) 0.027945041656494 (glob time) So I can honestly recommend opendir if you plan on including the files in the dir. ---- Server IP: 69.147.83.197 Probable Submitter: 208.101.216.113 ---- Manual Page -- http://www.php.net/manual/en/function.glob.php Edit -- https://master.php.net/note/edit/79396 Del: integrated -- https://master.php.net/note/delete/79396/integrated Del: useless -- https://master.php.net/note/delete/79396/useless Del: bad code -- https://master.php.net/note/delete/79396/bad+code Del: spam -- https://master.php.net/note/delete/79396/spam Del: non-english -- https://master.php.net/note/delete/79396/non-english Del: in docs -- https://master.php.net/note/delete/79396/in+docs Del: other reasons-- https://master.php.net/note/delete/79396 Reject -- https://master.php.net/note/reject/79396 Search -- https://master.php.net/manage/user-notes.php
