PHP traverses TXT files in a directory and sorts them by time

Traverse txt files in the directory

Example:

//遍历目录下文件方法 function printdir($dir) { $files = array(); //opendir() 打开目录句柄 if($handle = @opendir($dir)){ //readdir()从目录句柄中（resource，之前由opendir()打开）读取条目, // 如果没有则返回false while(($file = readdir($handle)) !== false){//读取条目 if( $file != ".." && $file != "."){//排除根目录 if(is_dir($dir . "/" . $file)) {//如果file 是目录，则递归 $files[$file] = printdir($dir . "/" . $file); } else { //获取文件修改日期 $filetime = date('Y-m-d H:i:s', filemtime($dir . "/" . $file)); //文件修改时间作为健值 $files[$filetime] = $file; } } } @closedir($handle); return $files; } }

Sort by time based on the returned array

Example:

//根据修改时间对数组排序 function arraysort($aa) { if( is_array($aa)){ ksort($aa); foreach($aa as $key => $value) { if (is_array($value)) { $arr[$key] = arraysort($value); } else { $arr[$key] = $value; } } return $arr; } else { return $aa; } } $dir = "/php"; //输出 /php 下所有文件 print_r(arraysort(printdir($dir)));
