The problem is that exec() is looking for an immediate output and since I am
calling a command line program it doesn't return fast enough for it (I
think). The popen or fopen looks like it would work, but I don't understand
how to execute the command. Ie.
<?php
$cmd = "ls -la"
$lines = file ($printers);
while (list ($line_num, $line) = each ($lines)) {
$trimline = trim ($line);
$fp = popen ("$cmd", "r");
exec($fp)
echo "npadmin output: $output\n";
pclose ($fp);
}
?>

exec() can capture ALL output from a command if you supply an array as the
second argument to it

Good day,
exec() isn't very good at capturing output. It will only return the last
line of output, which is designed mostly to capture error conditions.
You would be best off using popen() and attaching a pipe to the output, and
then just read from the pipe. More information can be found about popen()
with PHP's documentation.
Try that instead.

I am trying to do a match for an expression and it to a variable from the
output of a command:
<?php
$lines = file ($file);
while (list ($line_num, $line) = each ($lines)) {
$trimline = trim ($line);
$output = shell_exec ("$prog $cmdline $trimline &");
}
?>
How can look through $output to set the information returned as different
variables the output would look like:
variable1:"some information" variable2:"some information"
I want to set each variable to a string and write it to a file.
Thank You for you help.
Roy
