print_r不会转到下一行

Question

I'm trying to run a bash script in php; also, i want to see the log of the bash script. So, my php file looks like something like this:

<?php
    $message=shell_exec("/var/www/html/judge/uploads/MyScript.sh 2>&1");
    print_r($message);
?>

"Myscript.sh" is this :

    #!/bin/bash
    printf "MyScript \nran \nsuccesfully"

And the output is:

MyScript ran successfully 

But i want the output to be something like this:

MyScript
ran
successfully

What should i do?

As per my comment:

If you view your HTML source, you will see the line breaks are indeed there. If you want to see them on different lines "on screen", you need to use either <br> or nl2br() .
