bool posix_mkfifo(string $pathname, int $mode)
posix_mkfifo() creates a special FIFO file which exists in the file system and acts as a bidirectional communication endpoint for processes.
TRUE on success or
FALSE on failure.
- string $pathname: Path to the FIFO file.
- int $mode: The second parameter
modehas to be given in octal notation (e.g. 0644). The permission of the newly created FIFO also depends on the setting of the current umask(). The permissions of the created file are (mode & ~umask).
- When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script that is being executed.
