system() replaced with exec().
system() emits the output to STDOUT, but that is trapped
by PHP when running system. PHP then prints the output of the command
when using the "system" function call and returns the last line (which the
OP then echoes).

Interesting. On 2.2.x it is using popen rather than either system or exec. Wonder why that was changed away from popen.
There is still an extra blank line at the end of the output, looks like it's a bunch of indentation before the closing pre tag.
