Hi, I have problem of open named pipe file in linux.
Here is my sample code:
$fifo_file = "/dev/pmsg";
@ $fp = fopen($fifo_file, 'w+b');
if(!$fp) {
echo "open ".$fifo_file." failed";
}
else {
$msg_cmd = "ttttttt";
fwrite($fp, $msg_cmd, strlen($msg_cmd));
fclose($fp);
}
There is an other program which is waiting for messages from /dev/pmsg
forever. You could also test it by running `cat /dev/pmsg` in shell
console.
Every one have permissions of read and write for /dev/pmsg
prw-rw-rw- 1 root root 0 12-08 10:13 /dev/pmsg
Environment info: php-5.1.2-5, httpd-2.2.0-5.1.2, OS: Redhat FC5
Thanks in advance,
Mike
Are you getting any errors? What if you remove the @ from the start of
line 2, any errors now?
