Bug description: fclose(STDIN|STDOUT|STDERR) has no effect
Description:
------------
I am trying to run a simple PHP script in the background (as a daemon)
using the PHP 5 CLI. I first set the execution time limit to 0 (no limit),
and then I attempt to close STDIN, STDOUT, STDERR using fclose(), but the
pipes are _NOT_ being closed.
This problem seems quite similar to bug #27865, which is labelled as
"fixed", but the behaviour I am getting in this instance is not as
documented.
Reproduce code:
---------------
set_time_limit(0);
fclose(STDIN);
fclose(STDOUT);
fclose(STDERR);
sleep(...sync timing with system clock...);
while (TRUE) {
system(...generate call...);
sleep(...sleep some more...);
} // END while
Expected result:
----------------
After invocation from the command line, the program should close all STD
pipes, and run in the background. A new prompt should appear in the shell,
ready to accept my next command while the PHP script is running in the
background without open pipes to my current terminal.
Actual result:
--------------
A new command prompt does not appear, instead the terminal hangs in
suspense waiting for the process to complete. The script is designed to
run forever in a tight loop. Hitting Ctrl+C gets the command prompt back,
but interrupts and kills the PHP process.
I can get the desired result by using I/O tricks from the command line:
./script.php &
But, this solution has limitations.
