PHP Sample To Upload File With Custom Form

Before you try this code, make sure you have installed PHP cURL,
This sample uses FileCloud APIs "loginguest" and "upload"
This code creates custom upload form doing a single shot upload
This can be modified for multiple uploads as well
The code can upload files with same name as input or a custom name.
The following sample reads a file named helloworld.txt and uploads into FileCloud as hellothere.txt

<?php

function create_upload_form_for_datachunk($data) {
    $headers = array();
    $form[] = implode("\r\n", array(
        "Content-Disposition: form-data; name=\"filedata\"; filename=\"blob\"",
        "Content-Type: application/octet-stream",
        "",
        $data,
        "blob"
    ));

    // generate safe boundary 
    do {
        $boundary = "---------------------" . md5(mt_rand() . microtime());
    } while (preg_grep("/{$boundary}/", $form));

    // add boundary for each parameters
    array_walk($form, function (&$part) use ($boundary) {
        $part = "--{$boundary}\r\n{$part}";
    });

    // add final boundary
    $form[] = "--{$boundary}--";
    $form[] = "";

    // set options
    $headers[] = "Content-Type: multipart/form-data; boundary={$boundary}";
    return array($headers, $form);
}
