<?php
ini_set("max_execution_time",);

$ftp_server = "192.168.1.1";
$ftp_user = "haven";
$ftp_pass = "haven";

// set up a connection or die
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server");

// try to login
if (@ftp_login($conn_id, $ftp_user, $ftp_pass)) {
echo "Connected as $ftp_user@$ftp_server\n";
} else {
echo "Couldn't connect as $ftp_user\n";
}

if(ftp_chdir($conn_id,"/home/haven")){

ftp_pasv($conn_id, true);
if(ftp_get ($conn_id, "abc.zip", "abc.zip",FTP_BINARY)){
echo "123";
}

}else{

echo "false";

}

ftp_close($conn_id);

?>
