Iată o explicație pe scurt a directivelor de configurare.

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.

Notă:

This option was introduced immediately after the release of version 4.0.3. For versions up to and including 4.0.3 you can only disable this feature at compile time by using the configuration switch --disable-url-fopen-wrapper.

Avertizare

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 Funcții GD și Image extension.

allow_url_include boolean

This option allows the use of URL-aware fopen wrappers with the following functions: include, include_once, require, require_once.

Notă:

This setting requires allow_url_fopen to be on.

user_agent string

Define the user agent for PHP to send.

default_socket_timeout integer

Default timeout (in seconds) for socket based streams.

Notă: This configuration option was introduced in PHP 4.3.0

from string

The email address to be used on unauthenticated FTP connections and as the value of From header for HTTP connections, when using the ftp and http wrappers, respectively.

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.

Notă: This configuration option was introduced in PHP 4.3.0

I'm surprised this isn't mentioned in docs here, but to set these values at runtime use "ini_set()". For example:

<?php
ini_set
("auto_detect_line_endings", true);

// Now I can invoke fgets() on files that contain silly \r line endings.
?>

Just a quick note: setting default_socket_timeout to zero causes file_get_contents(<url>) to immediately fail.

We were under the (false) impression that zero meant never time out.
