Title
allow_url_fopenboolThis 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.
allow_url_includeboolThis option allows the use of URL-aware fopen wrappers with the following functions:
include(),include_once(),require(),require_once().NoteThis setting requires allow_url_fopen to be on.
user_agentstringDefine the user agent for PHP to send.
default_socket_timeoutintDefault timeout (in seconds) for socket based streams. Specifying a negative value means an infinite timeout.
fromstringThe 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_endingsboolWhen turned on, PHP will examine the data read by
fgets()andfile()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.
WarningThis option has been deprecated as of PHP 8.1.0.
