Read Bytes of a File in a String

Question

Simple Theorical Question :

To Upload a File to the Server Using Php , i choosen this Mechanism(if Possible) :

Read Bytes of the File , Put it in a String as Simple Text , then Post it to the Server as a Simple Text Message($_REQUEST) , Then write this 'Text' to a New File on the Server ,

So my Question is :

How can i read Bytes of a File and Store it in a String/StringBuilder 'As they are' as Simple Text ?

you ca send content via ajax call to the server, but with javascript, it will be difficult to access local file — MatRt, Mar 12 '13 at 13:09
oops sorry now get your meaning ! but your question is little bit confusing — Deep123, Mar 12 '13 at 13:10
it's not good idea. send file location. then upload it. first do a search on how to upload a file from android. — Akshay Deep Giri, Mar 12 '13 at 13:13
Thanks all for your Answer , Bytes mean something like this "jivgfuor_ç'_è"è_-é"ç_àè$$$$"'(-"à(çé")à(_éç_'àç" , i want to Read the Bytes , Store in a String , Send this String to the Server as Simple Text Message , then Write into a New File — Nikita, Mar 12 '13 at 13:19
Sorry if its a little Confusing , its like when you Open an Audio File for Example with NotePad , Copy its Content to a New File then Rename as .mp3 or .wav , if its Technically Possible ? — Nikita, Mar 12 '13 at 13:21

you can use file_get_contents it's binary safe.

$binaryContent = file_get_contents('path/to/file');

If you get problems sending the content than encode it:

$binaryContent = base64_encode($binaryContent);

But I would use curl to upload a file:

From php.net http://www.php.net/manual/de/function.curl-setopt.php

/* http://localhost/upload.php:
print_r($_POST);
print_r($_FILES);
*/

$ch = curl_init();

$data = array('name' => 'Foo', 'file' => '@/home/user/test.png');

curl_setopt($ch, CURLOPT_URL, 'http://localhost/upload.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl_exec($ch);
