XXX. Filesystem Functions
Introduction
Requirements
No external libraries are needed to build this extension,
but if you want PHP to support LFS (large files) on Linux,
then you need to have a recent glibc and you need compile
PHP with the following compiler flags: -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64.
Installation
There is no installation needed to use these functions;
they are part of the PHP core.
Runtime Configuration
The behaviour of these functions is affected by settings
in php.ini.
