Al you have to do is say which color you want to be transparent.

The reason why popen() does not work for you is because you are calling
popen() with the wrong set of arguments.
You need to specify the they way you want to use the pipe.
You read a command just like a file, typically like:
$cmd = "dir *.txt 2>NUL"; // supress stderr
if ($pipe = popen($cmd, "r")) {
while (!feof($pipe)) {
// do your stuff
}
} else {
// if needed, do some error handling
}
USAGE:
According to the manual you can't use fread() with the popen():
"Returns a file pointer identical to that returned by fopen(), except that
it is unidirectional (may only be used for reading or writing) and must be
closed with pclose(). This pointer may be used with fgets(), fgetss(), and
fwrite()."
check out http://www.php.net/popen for details.
BIDIRECTIONAL COMMANDS:
As stated in the manual, you can only open the pipe for eitehr reading or
(an exlusive or) writing. Hence popen() will not help you here, in such case
you should use proc_open().

Subject: RE: [PHP-WIN] Prevent error output from shell_exec
I'm calling ps_exec.
$handle = popen($cmd);
$read = fread($handle, 2096);
echo $read;
pclose($handle);
Does nothing whereas system($cmd) or shel_exec($cmd) works fine, apart
from the output. $read outputs nothing when I tested it. When calling
popen, can you pass program parameters such as "dir *.tmp /p" ? Maybe
this is why it's not working. The $cmd I call has rather a lot of
command line parameters to go with it.

Subject: RE: [PHP-WIN] Prevent error output from shell_exec
I can guarante you that popen() does work - I use it myself on a win2003
server. Since you can use shell_exec() I assume this has nothing to do
with safe_mode being switched on.
How do you call popen() ands what kind of dos program are you calling?

That did the trick.
Many thanks!

Hi all,
I'm hoping to install phpdocumentor which I have down-loaded as a 'tgz'
file to my windows machine. I'm not actually familiar with tgz files and
have no idea what I'm actually meant to do with it.
What does one do with a tgz file?
