-         Set the order of the EGPCS (Environment, GET, POST, Cookie,
-         Server) variable parsing. The default setting of this
-         directive is "EGPCS". Setting this to "GP", for example,
-         will cause PHP to completely ignore environment variables,
-         cookies and server variables, and to overwrite any GET
-         method variables with POST-method variables of the same name.
+         Sets the order of the EGPCS (<literal>E</literal>nvironment, 
+         <literal>G</literal>et, <literal>P</literal>ost, 
+         <literal>C</literal>ookie, and <literal>S</literal>erver) variable 
+         parsing. For example, if variables_order 
+         is set to <literal>"SP"</literal> then PHP will create the 
+         &link.superglobals; <varname>$_SERVER</varname> and 
+         <varname>$_POST</varname>, but not create 
+         <varname>$_ENV</varname>, <varname>$_GET</varname>, and 
+         <varname>$_COOKIE</varname>.  Setting to "" means no 
+         &link.superglobals; will be set.

-         See also <link linkend="ini.register-globals">register_globals</link>.
+         If the deprecated 
+         <link linkend="ini.register-globals">register_globals</link> 
+         directive is on (removed as of PHP 6), then variables_order also 
+         configures the order the <literal>ENV</literal>, 
+         <literal>GET</literal>, <literal>POST</literal>, 
+         <literal>COOKIE</literal> and <literal>SERVER</literal> variables 
+         are populated in global scope. So for example if variables_order 
+         is set to <literal>"EGPCS"</literal>, register_globals is enabled, 
+         and both <varname>$_GET['action']</varname> and
+         <varname>$_POST['action']</varname> are set, then  
+         <varname>$action</varname> will contain the value of 
+         <varname>$_POST['action']</varname> as <literal>P</literal> comes 
+         after <literal>G</literal> in our example directive value.

+          The content and order of
