Hi, let's say i have the following:

$vars="name=david&age=26&sport=soccer&birth=1984";

I want to turn this into real php variables but not everything. By example, the functions that i need :

$thename=getvar($vars,"name");
$theage=getvar($vars,"age");
$newvars=cleanup($vars,"name,age"); // Output $vars="name=david&age=26"

How can i get only the variables that i need . And how i clean up the $vars from the other variables if possible?

Thanks
