PHP:删除任何扩展名的文件？

Question

当用户上传照片时,它会检查是否已有照片; 如果他们这样做,我希望它删除旧的(可能有任何扩展名),然后把新的.有没有办法在没有从数据库中获取旧扩展的情况下执行此操作？目前代码:

        $del = $members->prepare("insert into profiles(userid, path, width, height, type, rtu, ext) values(?, ?, ?, ?, ?, ?, ?) 
                                    ON DUPLICATE KEY UPDATE path = ?, width = ?, height = ?, type = ?, rtu = ?, ext = ?, time = NOW()");
        $del->bind_param('sssssssssssss', $_SESSION['token'], $title, $file_info[0], $file_info[1], $file_info[2], $rh, $extension, 
        $title, $file_info[0], $file_info[1], $file_info[2], $rh, $extension);

        $del->execute();

        $new_file_name = "bb-x".$_SESSION['token'].".".$extension;

        if ($del->affected_rows > 0) {

            unlink('profiles/bb-x62'<any extension>);
        }

        $move_file = move_uploaded_file($file['tmp_name'], $upload_image_to_folder.$new_file_name);

Answer 1

代替 unlink('profiles/bb-x62'<any extension>);

使用这两行:

$file_pattern = "profiles/bb-x62.*" // Assuming your files are named like profiles/bb-x62.foo, profiles/bb-x62.bar, etc.
array_map( "unlink", glob( $file_pattern ) );

这应该够了吧.
