重命名文件名

Question

我正在使用以下脚本重命名文件夹中的图像。执行时，前 2 个（新）名称失败，因此它基本上以 3.

开头

    function getFileExtension($filename){   
        return substr($filename, strrpos($filename, '.'));
    }
    
        
    $counter    =   1;
    
if ($handle = opendir('images')) {
    
    while (false !== ($fileName = readdir($handle))) {
        $newCounter = str_pad($counter, 3, '0', STR_PAD_LEFT);
        $prefix =   '11225';
        $newName = $prefix.$newCounter;
        rename('images/'.$fileName, 'images/'.$newName.getFileExtension($fileName));
        $counter++;
        
    }
    
    closedir($handle);

}

这些是我收到的警告，

Warning: rename(images/.,images/11225001.): The process cannot access the file because it is being used by another process. (code: 32) in C:\wamp\apache2\htdocs\renameimages\index.php on line 21

Warning: rename(images/..,images/11225002.): Access is denied. (code: 5) in C:\wamp\apache2\htdocs\renameimages\index.php on line 21

有什么我遗漏的吗？

Answer 1

前两个是指向当前文件夹和父文件夹的链接。你应该跳过它们。

if($fileName=='.' || $filename=='..')continue;
