PHP statistics directory of files and directories in the directory size method,

The examples in this article describe the files in the PHP statistics directory and the size of directories in the directory. Share to everyone for your reference, as follows:

<?php//loops through all the files in the directory and counts the size of directories and files $dirName = "PhpMyAdmin"; $dir =opendir ($dirName); Returns a resource type while ($fileName =readdir ($dir)) {$file = $dirName. " /". $fileName; if ($fileName! = "." && $fileName! = "...") {if (Is_dir ($file)) {echo "". $fileName. " = = = ". Date (" Y-m-d h:i:s ", Filectime ($file))." = = ". FileType ($file)." = = ". Tosize (Dirsize ($file))."
"; } else{echo "". $fileName. " ===== ". Date (" Y-m-d h:i:s ", Filectime ($file))." = = = ". FileType ($file)." = = = ". Tosize (FileSize ($file))."
"; }}} closedir ($dir);  Convert the size of a file or directory into an easy-to-read way function tosize ($size) {$DW;//Specify the unit of file or directory statistics if ($size >pow (2,30)) {$DW = "GB"; $size =round ($size/pow (2,30), 2);  } else if ($size >pow (2,20)) {$DW = "MB"; $size =round ($size/pow (2,20), 2);  } else if ($size >pow (2,10)) {$DW = "KB"; $size =round ($size/pow (2,10), 2); } else {$dw = "bytes";} return $size. $dw; }//Use recursion to count the size of the directory function dirsize ($dirName) {$dirsize =0; $dir =opendir ($dirName); while ($fileName =readdir ($dir)) {$ file= $dirName. "  /". $fileName; if ($fileName! = "." && $fileName! = "...")  {//must be judged, otherwise an error will occur if (Is_dir ($file)) {$dirsize +=dirsize ($file);  } else{$dirsize +=filesize ($file); }}} closedir ($dir); return $dirsize; }?>
