试试我为这样的任务编写的这个函数。它是为与本地文件系统一起工作而设计的,但ftp://
只要您的系统已allow_url_fopen
启用,它就可以与 URL 一起工作(尽管DIR_SORT_ATIME
并且DIR_SORT_CTIME
不会工作):
// Constants to make usage more reader-friendly
define('DIR_SORT_NAME', 1);
define('DIR_SORT_SIZE', 2);
define('DIR_SORT_ATIME', 3);
define('DIR_SORT_MTIME', 4);
define('DIR_SORT_CTIME', 5);
function readdir_sorted_array ($dir, $sortCol = DIR_SORT_NAME, $sortDir = SORT_ASC) {
// Validate arguments
$dir = rtrim(str_replace('\\', '/', $dir), '/');
$sortCol = (int) ($sortCol >= 1 && $sortCol <= 5) ? $sortCol : 1;
$sortDir = ($sortDir == SORT_DESC) ? SORT_DESC : SORT_ASC;
$name = $size = $aTime = $mTime = $cTime = $table = array();
// Open the directory, return FALSE if we can't
if (!is_dir($dir) || (!$dp = opendir($dir))) return FALSE;
// Fetch a list of files in the directory and get stats
for ($i = 0; ($file = readdir($dp)) !== FALSE; $i++) {
if (!in_array($file, array('.','..'))) {
$path = "$dir/$file";
$row = array('name'=>$file,'size'=>filesize($path),'atime'=>fileatime($path),'mtime'=>filemtime($path),'ctime'=>filectime($path));
$name[$i] = $row['name'];
$size[$i] = $row['size'];
$aTime[$i] = $row['atime'];
$mTime[$i] = $row['mtime'];
$cTime[$i] = $row['ctime'];
$table[$i] = $row;
}
}
// Sort the results
switch ($sortCol) {
case DIR_SORT_NAME:
array_multisort($name, $sortDir, $table);
break;
case DIR_SORT_SIZE:
array_multisort($size, $sortDir, $name, SORT_ASC, $table);
break;
case DIR_SORT_ATIME:
array_multisort($aTime, $sortDir, $name, SORT_ASC, $table);
break;
case DIR_SORT_MTIME:
array_multisort($mTime, $sortDir, $name, SORT_ASC, $table);
break;
case DIR_SORT_CTIME:
array_multisort($cTime, $sortDir, $name, SORT_ASC, $table);
break;
}
// Return the result
return $table;
}
返回给定路径中文件的排序关联数组$dir
。
