Piping shell_exec output

[byteware]

I'm using PHP 4.3.2 (cli). I'm writing a shell script.

I have need to run a shell command that takes stdin as it input (this works just fine) AND
take that output as the input to another command.

I run the first command with

$myoutput = shell_exec(command1);

I would like to feed $myoutput to the stdin of command2.

How do I do this?

From the command line you could use

command2 < textfile,

so perhaps

$myoutput = shell_exec(command1);
shell_exec ("command2 < $myoutput");

I donot want to write an intermediate file. I would like to keep everything in memory.

Yes, this is close - however the output may (and does) contain ")" that create errors.
