PHP Unzip after FTP Upload - php

Question

I have these lines of code which uploads a file via FTP. After uploading, I need to unzip the file. Problem encountered was, the file is successfully uploaded but I cannot unzip it. Can anyone help me with this?
if(isset($_POST['submit'])){
$file = $_FILES['uploaded_file']['name'];
$remote_file = $_FILES['uploaded_file']['name'];
$ftp_server = "1xx.xx.xx.xx";
$ftp_user_name = "xxuser";
$ftp_user_pass = "xx2016";
$toform2 = "FormType/Upload/";
$tounzip2 = "Unzip/";
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
ftp_pasv($conn_id, true);
// upload the file
$ftype = substr ($file,0,2);
if ($ftype == "F2") {
ftp_chdir ($conn_id,$toform2);
$upload = ftp_put($conn_id,$remote_file,$file,FTP_ASCII);
$file_path = $toform2;
// check upload status
if($upload){
// Unzip file
$zip = new ZipArchive();
$x = $zip->open($toform2);
if ($x === true) {
ftp_chdir ($conn_id,$tounzip2);
$zip->extractTo($tounzip2);
$zip->close();
echo "success"."</br>";
}else{
echo "fail";
}
//echo "Uploaded $source_file to $ftp_server as $destination_file" ;
}else{
//echo "FTP upload has failed!" ;
}
}

If the script has SSH access to the remote server, you can ssh2-exec a remote script to unzip your file.
SSH2-Connect:
http://php.net/manual/en/function.ssh2-connect.php
SSH2-Exec:
http://php.net/manual/en/function.ssh2-exec.php
First upload your file using FTP. (SFTP would be better)
Open an SSH connection and execute the unzip command remotely.
