[rrd-users] Re: php bindings for rrdtool

Here is the RRD.inc class I wrote for one of my PHP projects.  It spawns
the RRD process on instantiation, and keeps it open till descruction.
I've been using it for years with a very heavy load app with no
problems.  It's written for PHP4, so some modifications might be needed
for PHP5, specifically with the destructor.  But if you code your app
right, it will let you run multiple commands with one rrd fork exec.
Just make sure you don't prematurely destruct the object.

include('RRD.inc');
$rrd = new RRD;
$ret = $rrd->cmd('a_valid_rrd_command');
$ret = $rrd->graph('a_valid_rrd_graph_command');

graph() just calls cmd(), but it will parse out the image info from the
return value and return a <img/> tag.  cmd() returns the output from the
rrd process.

You can get it from http://os.cyberheatinc.com/RRD.inc.phps.  Feel free
to modify it to your liking, it's GPL.
