Well, I really do appreciate the help; maybe I'm misunderstanding
something. Using your statement above and executing the php script from
bash, I first get the results of your echo statement:
cmd is:<br>/bin/echo
. . . then the $mime_string, and then on the last line,
| /usr/bin/metamail -d -q -r -w -x -y <p><br>
After your echo statement, the fpassthru($cmd) results come back:
<b>Warning:</b> Supplied argument is not a valid File-Handle resource in
<b>./mimescript_test.php</b> on line <b>9</b><br>
The entire contents of this mimescript_test.php are:
---------------------------------------------------
#!/usr/local/bin/php -q
<?php
$fp0 = fopen('php://stdin','r') or die("couldnt open stdin");
while(!feof($fp0)) {
$mime_string .= fgets($fp0,4096);
}
$cmd='/bin/echo' ." $mime_string | /usr/bin/metamail -d -q -r -w -x -y
";
echo ' cmd is:<br>', $cmd, '<p>';
fpassthru($cmd);
?>
----------------------------------------------------
As it seems fpassthru is supposed to work with the file pointer rather
than string, I did try using $fp0 rather than $mime_string, but I got
"not a valid File-Handle resource".
If I substitute exec for fpassthru and add a $return to capture what
comes back, I get an empty array (I get a response of "Array" when
attempting to echo the $return variable, when I echo $return[0], etc., I
get nothing.
If I substitute system for fpassthru, I get only "127" when I echo the
$return.
I'm not the expert, but it certainly seems the problem lies in getting
the /bin/echo command pipe the string to metamail, and I'm not certain
how to make it do so.
