Help with exec.

I need to pipe some data to an external application.

I have this:

while ($row = mysql_fetch_array($theData[0])) {
$src_ip[] = $row[0];
$dst_ip[] = $row[1];
$sig_desc[] = $row[2];

$rec ++;
if ( $rec == $recCount ) {
break;
}
}

for ($i = 0; $i < sizeof($src_ip); $i++) {
$tmpResult[] = "$sig_desc[$i],$src_ip[$i],$dst_ip[$i]\n";
}


The external program is called like:

cat results.csv | theprogram outputfilename

Is there a way mimic this w/o outputting $tmpResult to a file first?

Thanks.

I believe you can use popen() to open "theprogram" and pipe to it the
content and read back the results. All without writing to any files.

popen() either reads from a pipe or writes to a pipe, if I remember
well, not both. Teus.

Re: Help with exec.

I work by example :)

I can't find enough of an example to get me going with this.

I have this:

$glow =3D popen('afterglow.pl -c color.properties -s -e 3 -p 1 -l 2000 |
neato -Tpng -o /usr/local/www/test.png','r');

how do I feed my array to that?

Thanks.

Hi,

I have used this code to feed data to gpg and read back the encrypted
result, Im sure you can adapt it to your needs.

function Encrypt($data){

# http://www.theoslogic.com/scripts/php-gpg/

$gpg_command="/usr/bin/gpg $parameters";

$errLog = "/tmp/errors.log";

$dspecs = array(
0=>array("pipe", "r"),
1=>array("pipe", "w"),
2=>array("file", $errLog, "a")
);

$encrypted="";
$procdata="";

$gpgproc = proc_open($gpg_command, $dspecs, $pipes);

if (is_resource($gpgproc)) {
fwrite($pipes[0], $data);
fclose($pipes[0]);

while($procdata = fgets($pipes[1], 1024)) {
$encrypted .= $procdata;
}
fclose($pipes[1]);
}

return $encrypted;
}

It works really well.

Regards

Ian

Re: Re: Help with exec.

and its that easy!

it took me a minute to figure out; but all I had to do was:

if (is_resource($process)) {

for ($i =3D 0; $i < sizeof($src_ip); $i++) {
fwrite($pipes[0], "$sig_desc[$i],$src_ip[$i],$dst_ip[$i]\n");
}

fclose($pipes[0]);
fclose($pipes[1]);
proc_close($process);
}

thanks.
