     extensions, the PHP version, server information and environment

>&#13;     Because every system is setup differently,
     <B

>configuration settings</A
> and for
     available <A
HREF="language.variables.predefined.html"
>predefined
     variables</A
> on a given system.  Also,
     <B
CLASS="function"
>phpinfo()</B
> is a valuable debugging tool as it
     contains all EGPCS (Environment, GET, POST, Cookie, Server) data.
    </P

>&#13;     The output may be customized by passing one or more of the

> bitwise values summed
     together in the optional <TT

     One can also combine the respective constants or bitwise values
     together with the <A
