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:

 "; } 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; }?>
