Upload files without using php but no php form - php

Question

I have a C program running on the localhost server which generates some files( writes its output to these file). Then I zip all these files together using php. Now I want to upload the zip file produced to mysql server using some php script but i dont want the user to upload these files using a form by clicking choose file button but i would like to upload these automatically as soon as they are generated to mysql using php script.
<?php
//get content of json file
require_once("zip.php");
$str = file_get_contents("program/heatmap_parameters.json");
//decode the JSON
$json = json_decode($str,true);
//echo '<pre>' . print_r($json, true) . '</pre>';
foreach ($json['parameters'] as $params) {
echo $params[3]."<br>";
$files_to_zip = array("program/".$params[3]);
var_dump($files_to_zip)."<br>";
//$files_to_zip = array("program/cctv2.mp4.json");
//if true, good; if false, zip creation failed
$zip_name = "program/".$params[3].".zip";
//zip the files
$result = create_zip($files_to_zip,$zip_name);
}
//connect to database
require_once("database/conn.php");
//upload zip file to database without displaying any form.
?>
I need a way to upload my generated file to saved to mysql without choosing it from the form.
<form action="" method="post" enctype="multipart/form-data">
<table width="350" border="0" cellpadding="1" cellspacing="1" class="box">
<tr>
<td width="246">
<input type="hidden" name="MAX_FILE_SIZE" value="2000000">
<input name="userfile" type="file" id="userfile">
</td>
<td width="80"><input name="upload" type="submit" class="box" id="upload" value=" Upload "></td>
</tr>
</table>
</form>
<?php
if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0)
{
$fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fp = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);
include '../database/conn.php';
$sql = "INSERT INTO upload (name, content ) ".
"VALUES ('$fileName', '$content')";
$query = mysqli_query($conn,$sql);
if(!$query){
die("Cannot Insert".mysql_error());
}
}
How can i make this code such that it does not need the form

To answer your question in oneline,
You can not upload a file without form/input type file element, because that will a big security hole to web.
To upload any file to server, server need files object which has all the info of file. that info will be given by client from where you are uploading a file. It will also has the tmp location of file form where server will take that file.
You can copy file from one server to another, using curl or you can
write a bash script which will copy file from one place to another and
you can run that bash script using PHP.
Hope this helps to you!
