    Here’s a short explanation of the configuration

    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.

    allow_url_include boolean

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


    This setting requires allow_url_fopen to be on.


    Define the user agent for PHP to send.

    default_socket_timeout integer

    Default timeout (in seconds) for socket based

    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

    sys_temp_dir string
