Create a fifo special file (a named pipe) (PHP 4, PHP 5)
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.



Path to the FIFO file.


The second parameter mode has 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).

Return Values

Returns TRUE on success or FALSE on failure.



When safe mode is enabled, PHP checks whether the files or directories you are about to operate on have the same UID (owner) as the script that is being executed.
