Here's a new one:
<?php
exec("usr/bin/uptime", $result);
echo $result;
?>
Simple huh!?
So why is the output instead of the real uptime of the system just Array?
According to the function description at http://www.php.net/manual/en/function.exec.php the functions should spit out a string and not an array, shouldn't it!?
And why doesn't it print out the data, it only produces the array whatever output... argh!
What you want is
<?php
$result = exec("usr/bin/uptime");
echo $result;
?>
The last line is returned as a string. In this case that is all you care about, especially because it has 1 line.
If called like this
<?php
exec("usr/bin/uptime", $result);
echo $result[0];
?>
it puts ALL the lines of the result (what ever is printed to stdout) in the array, in order to directly access every line that is output, not just the last.
