I'm using php with global_register=On.

I'm using php with global_register=On and I wrote:

function set_session($ParamName, $ParamValue)
{
global ${$ParamName};
if(session_is_registered($ParamName))
session_unregister($ParamName);
else
{
${$ParamName} = $ParamValue;
session_register($ParamName);
}
}

and then I can use $ParamName with value was set by function set_session. But now I don't want to use global_register=On for security reason. How do I write with result is similar to using set_session function?

session_start();

function set_session('paramname', 'paramvalue')
{
$_SESSION['paramname'] = paramvalue;

if ( $SESSION['paramname'] )
unset($SESSION['paramname']
else
$_SESSION['paramname'] = 'paramvalue'
}

This should be close. As I a relatively new to PHP, check my syntax but I think the method is correct.
