how can i define variable

A pretty vague question :)  There are a million ways to define 
variables, for example:
  $foo = "somevalue";
  echo $foo;
  http://www.php.net/language.variables
Or, let's say you want to define a variable through the HTTP request, 
like through GET:
  http://www.example.com/yourscript.php?bar=somevalue
  echo $_GET["bar"];
  http://www.php.net/variables.external
Or maybe a cookie:
  setcookie("baz", "some value", time()+424242);
  echo $_COOKIE["baz"];
  http://www.php.net/setcookie
Or maybe you're a little confused about variable scope in PHP (you 
wouldn't be the first), consider this manual page:
  http://www.php.net/variables.scope
The manual discusses various ways to define variables, so be sure to 
read the manual.
