Ok I am having problems with a command I would like to execute through PHP.
I have tried simple backtick operators on the command, passthru, exec,
system all with the same results of 0 return code.
Here is an example of the command I am attempting to execute if someone
could provide me with some insight, examples etc.
/usr/bin/dnssec-keygen -a HMAC-MD5 -b 128 -n USER key (which works from
a terminal)
Here is my php code (I am changing into a writable directory which works
fine):
chdir( $defined['keys'] );
$cmd = $defined['dnssectool'] . " -a " . $algorithm . " -b " . $key_bit
. " -n USER " . $key_name;
echo $cmd . "<br>";
system( '$cmd', $ret );
chdir( $defined['virpath'] );
