从php获取matlab独立应用程序输出

Question

I have converted my .m file into a standalone application with the aid of deploytool.

Now, I want to run my application and get the outputs using PHP. I can run my application on cmd. And it will return the outputs and print. But I can not get the outputs from PHP.

this is the main file of my standalone application:

function [onsets,pitch,endpoint] =  matxtwavtomidi( input_args )

input=strsplit(input_args);
[s wavFs] = audioread(input{1});
[onsets,pitch,endpoint]=txtwavtomidi(s);

end

this is the result I get from cmd:

C:\Users\user> START /WAIT D:/java/matlab/matxtwavtomidi.exe D:/song.wav

onsets =
    1.7183
    1.7183
    2.3220
    2.3220

pitch =
    60
    72
    62
    74

endpoint =
    1.8576
    1.9040
    3.0650
    2.4149

this is my PHP:

<?php
$stringcmd= "START /WAIT D:/java/matlab/matxtwavtomidi.exe ";
$stringwav = "D:/song.wav";

exec($stringcmd.$stringwav, $output, $return_var);

echo $stringcmd.$stringwav;
var_dump($output);
var_dump($return_var);

?>

this is the result from php:

START /WAIT D:/java/matlab/matxtwavtomidi.exe D:/song.wav
array(0) { }
int(0)

Everytime when i run the application on cmd, it will always show the application's icon picture in the middle of the screen for 2 seconds and then disappear.

And when I run my PHP, it did show the icon picture,so I think it did run the application. And there are no error in php_error_log and apache error_log.

My problem is,why can't my PHP get the outputs of the application from cmd? And how to solve this problem?

(Sorry for my poor English..)

One good solution is to write your data from matlab to a .txt file and then read that file from your server side.. Hope it helps
