code in the action

        $target_dir  = $_SERVER['DOCUMENT_ROOT']."/zip_files/";
        $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
        $uploadOk = 1;
        move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);

Answer 1

Php does not restrict file upload types. All the file types are supported.

But there are certain configuration related to uploads like file_upload, max_file_uploads, upload_max_filesize

It could be possible that the zip file is going beyond the allowed limit.

There might be any problem in page in which you might be encrypting that zip

the code i have tried works like charm and it is as below

 <?php if($_POST){ $target_dir = $_SERVER['DOCUMENT_ROOT']; $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); $uploadOk = 1; move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file); } ?> <form action="index.php" method="post"enctype="multipart/form-data"> Select zip file to upload: <input type="file" name="fileToUpload" id="fileToUpload"> <input type="submit" value="Upload" name="submit"> </form> 

if it still doesn't work then check configuration parameters such as file_upload, max_file_uploads, upload_max_filesize in php.ini file
