批处理文件返回没有意义

Question

I have a batch file (batch.bat) with a simple echo.

`ECHO Hello world`

Then I use php to capture the output, But the output is not what I expected.

C:\wamp\www\postEnginInstruction>ECHO Hello world Hello world

Why do I not only get the Hello world?

PHP

     $output = shell_exec('batch.bat');
     print_r($output);

Answer 1

Try to use:

@ECHO Hello world

It seams PHP is also capturing commands. It is normal in long batch files to do:

@ECHO OFF
...

So commands are not displayed, just outputs.
