CXIII. POSIX Functions簡介This module contains an interface to those functions defined in the IEEE 1003.1 (POSIX.1) standards document which are not accessible through other means. POSIX.1 for example defined the open(), read(), write() and close() functions, too, which traditionally have been part of PHP 3 for a long time. Some more system specific functions have not been available before, though, and this module tries to remedy this by providing easy access to these functions.
安裝POSIX functions are enabled by default. You can disable POSIX-like functions with --disable-posix. 預定義常量以下常量由本增加模組定義,因此只有在本增加模組被編譯到 PHP 中,或是在運行時被動態加載後才有效。
