獲得目錄

Question

如何獲取最新的文件名，或者是添加到目錄中的文件路徑的最新文件除？

Answer 1

$path = "/path/to/my/dir"; 

$latest_ctime = 0; 
$latest_filename = '';  

$d = dir($path); 
while (false !== ($entry = $d->read())) { 
    $filepath = "{$path}/{$entry}"; 
    // could do also other checks than just checking whether the entry is a file 
    if (is_file($filepath) && filectime($filepath) > $latest_ctime) { 
    $latest_ctime = filectime($filepath); 
    $latest_filename = $entry; 
    } 
} 

// now $latest_filename contains the filename of the file that changed last 

Answer 2

列舉所有目錄中的文件，讓每個filemtime（），和你做。

Answer 3

$dir = dirname(__FILE__).DIRECTORY_SEPARATOR; 
$lastMod = 0; 
$lastModFile = ''; 
foreach (scandir($dir) as $entry) { 
    if (is_file($dir.$entry) && filectime($dir.$entry) > $lastMod) { 
     $lastMod = filectime($dir.$entry); 
     $lastModFile = $entry; 
    } 
}

如果在Linux上工作，看看http://us2.php.net/manual/en/book.inotify.php。這假設你讓腳本等待&在後臺登錄這些事件。

Answer 5

$dir = "/path/to/Your/dir";   
$pattern = '\.(zip|ZIP|pdf|PDF)$'; // check only file with these ext.   
$newstamp = 0;    
$newname = ""; 

if ($handle = opendir($dir)) {    
     while (false !== ($fname = readdir($handle))) {    
     // Eliminate current directory, parent directory    
     if (ereg('^\.{1,2}$',$fname)) continue;    
     // Eliminate other pages not in pattern    
     if (! ereg($pattern,$fname)) continue;    
     $timedat = filemtime("$dir/$fname");    
     if ($timedat > $newstamp) { 
      $newstamp = $timedat; 
      $newname = $fname; 
      } 
     } 
     } 
closedir ($handle); 

// $newstamp is the time for the latest file 
// $newname is the name of the latest file 
// print last mod.file - format date as you like    
print $newname . " - " . date("Y/m/d", $newstamp); 

Answer 6

filectime用於像chmod值這樣的元數據發生更改時。 filemtime用於實際內容更改。

Answer 7

我與PHP 5的解決方案：

$dir = "/path/to/Your/dir"; 
$arraydir =scandir($dir, 1); 
echo "arraydir 0: " . $arraydir[0] . "<br/>"; // 1. new file 
echo "arraydir 1: " . $arraydir[1] . "<br/>"; // 2. new file 
echo "arraydir elements: " . count($arraydir) . "<br/>";
