XXIII. Direct IO functions

Direct I/O Functions

PHP supports the direct io functions as described in the Posix Standard (Section 6) for performing I/O functions at a lower level than the C-Language stream I/O functions (fopen, fread,..).

Installation

To get these functions to work, you have to configure PHP with --enable-dio.
