posix_mkfifo

(PHP 3>= 3.0.13, PHP 4 )

posix_mkfifo --  Create a fifo special file (a named pipe)

Description

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.

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).

Замечание: Когда опция safe mode включена, PHP проверяет, имеет ли каталог, с которым вы собираетесь работать, такой же UID, как и выполняемый скрипт.
