I am trying to get certain output for svn command in XML format. Output is ok when I type valid parameters. However, when I type in wrong password, output does not show error message. This is the PHP code:

exec('/usr/bin/svn --username something --password something --non-interactive log -r HEAD --xml --verbose http://a51.unfuddle.com/svn/a51_activecollab/', $output);

Here is output I get in the terminal:

<?xml version="1.0"?>
<log>
svn: OPTIONS of 'http://a51.unfuddle.com/svn/a51_activecollab': authorization failed: Could not authenticate to server: rejected Basic challenge (http://a51.unfuddle.com)

And here is the output I get from the $output variable with var_dump:

array(2) {
[0]=>
string(21) "<?xml version="1.0"?>"
[1]=>
string(5) "<log>"
}

As you can see the $output variable does not return third line of output, where terminal does. Please help me to get the same output as I get in terminal (I even tried with shell_exec() or system() methods but they return the same output as exec()) How do I get full output? Thank you in advance!

You need to capture the stderr too.

Redirecting stderr to stdout should do the trick. Append 2>&1 to the end of your command.

e.g.

exec("/usr/bin/svn --username something --password something --non-interactive log -r HEAD --xml --verbose http://a51.unfuddle.com/svn/a51_activecollab/ 2>&1", $output);

This solved the problem. Thank you very much. –  Goran Oct 5 '10 at 13:40

Aside: isn't it bizarre that PHP's exec doesn't provide a simple way to capture the stderr output separately? –  Stephen C Jun 16 '13 at 2:31

You need to define a variable in which to store the message

$msg = exec('/usr/bin/svn --username something --password something --non-interactive log -r HEAD --xml --verbose http://a51.unfuddle.com/svn/a51_activecollab/');

That is probably not the solution, just a bad suggestion : have you tried to add an extra echo in the command:

exec('/usr/bin/svn --username something --password something --non-interactive log -r HEAD --xml --verbose http://a51.unfuddle.com/svn/a51_activecollab/;**echo ""**', $output);

And the other way to solve that is as already mentionned : if you don't have the last line in the $output, it is in the returned value of the exec() function anyway. You'd have then

$totalOutput = push($msg,$output);

with 

$msg = exec('/usr/bin/svn --username something --password something --non-interactive log -r HEAD --xml --verbose http://a51.unfuddle.com/svn/a51_activecollab/', $output);
