从php编写的Hostinger路径/文件名的格式是什么？

Question

尝试备份数据库时无法写入Hostinger文件。

我在下面所示的php片段中尝试过BACKUP_PATH的各种变化。

define("BACKUP_PATH", "/vuggles.co.uk/database/temp/atest.sql");
$server_name   = "localhost";
$username      = "myusername";
$password      = "mypasword";
$database_name = "mydatabasename";
$date_string   = date("Ymd");

$cmd = "mysqldump --routines -h {$server_name} -u {$username} -p{$password} 
{$database_name} > " . BACKUP_PATH . "{$date_string}_{$database_name}.sql";

exec($cmd);

目标文件'atest.sql'保持原始内容不变，并且没有创建新名称
