从ftp下载文件并保存在同一文件夹中

1）Download.php

<?php

// define some variables
$local_file = 'local.zip';
$server_file = 'server.zip';

// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

// close the connection
ftp_close($conn_id);

?>

2）设置一个Chronjob

假设您使用的是基于Debian的Linux发行版，则必须执行以下操作：

sudo crontab -e

插入这样的新行：

0/15 * * * php -f '/path/to/your/Download.php'
