Question

我正在尝试使用PHP从目录中删除给定文件。这是我试过的代码：

// Get the file name
$id = '61514';

// Get the folder path
$uploads_folder_dir = 'some/dir';

// Check if the directory exists
if ( ! file_exists( $uploads_folder_dir ) )
    return false;

// Open the directory
if ( $dir = opendir( $uploads_folder_dir ) ) {

    // Loop through each file in the directory
    while ( false !== ( $file = readdir( $dir ) ) ) {

        // Target the file to be deleted and delete. All files in folder are .png
        if ( $file == ( $id . '.png' ) )
            @unlink( $uploads_folder_dir . '/' . $file );
    }
}
// Housekeeping
closedir( $dir );
@rmdir( $uploads_folder_dir );

每次运行代码时，我尝试删除的特定文件都不会被删除。

我的猜测是当我循环遍历目录时，找到该文件的逻辑无法正常工作。我可以确认文件61514.png肯定在目录some/dir

中

希望有人能在这里发现我出错的地方？

Answer 1

为什么要循环浏览文件？这个会容易得多：

// Get the file name
$id = '61514';
// Get the folder path
$uploads_folder_dir = 'some/dir';
// Check if the directory exists
if ( ! file_exists( $uploads_folder_dir ) )
    return false;

unlink("$uploads_folder_dir/$id.png");

// Housekeeping
@rmdir( $uploads_folder_dir );

Answer 2

首先通过打印整个文件路径（如

）调试文件路径是否正常

// Target the file to be deleted and delete. All files in folder are .png
        if ( $file == ( $id . '.png' ) ){
             echo $uploads_folder_dir . '/' . $file; die;
             @unlink( $uploads_folder_dir . '/' . $file );
        }
    }

Answer 3

@unlink - ＆gt;使用unlink如果你没有看到权限被拒绝的问题，那么文件和＆＃34; dir＆＃34;应该删除。
