encoding from .txt file to string using php

I'm doing this project where I receive a .txt file from a MATLAB program in a PHP server. I would like to extract the data in the .txt file and encode it to a string to be sent by t开发者_JAVA技巧he server to an android. Any ideas on how to do that?

Screw the string.

readfile()

use below code for your task.

$file = file_get_contents('test.txt', true);
$parsed_str = json_decode($file);

I think it may be helpful to you..

Thanks.
