filepro -- Read and verify the map file

Description

bool filepro ( string directory )

This reads and verifies the map file, storing the field count and info.

No locking is done, so you should avoid modifying your filePro database while it may be opened in PHP.

XXXVIII. 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 .

Table 1. Filesystem and Streams Configuration Options

Name Default Changeable Changelog allow_url_fopen "1" PHP_INI_SYSTEM PHP_INI_ALL in PHP <= 4.3.4. Available since PHP 4.0.4. user_agent NULL PHP_INI_ALL Available since PHP 4.3.0. default_socket_timeout "60" PHP_INI_ALL Available since PHP 4.3.0. from NULL ??   auto_detect_line_endings "0" PHP_INI_ALL Available since PHP 4.3.0.

Here's a short explanation of the configuration directives.

allow_url_fopen boolean

This option enables the URL-aware fopen wrappers that enable accessing URL object like files. Default wrappers are provided for the access of remote files using the ftp or http protocol, some extensions like zlib may register additional wrappers.

Warning

On Windows versions prior to PHP 4.3.0, the following functions do not support remote file accessing: include() , include_once() , require() , require_once() and the imagecreatefromXXX functions in the Reference LIV, Image Functions extension.

user_agent string

Define the user agent for PHP to send.

default_socket_timeout integer

Default timeout (in seconds) for socket based streams.

from string

Define the anonymous ftp password (your email address).

auto_detect_line_endings boolean

When turned on, PHP will examine the data read by fgets() and file() to see if it is using Unix, MS-Dos or Macintosh line-ending conventions.

This enables PHP to interoperate with Macintosh systems, but defaults to Off, as there is a very small performance penalty when detecting the EOL conventions for the first line, and also because people using carriage-returns as item separators under Unix systems would experience non-backwards-compatible behaviour.
