Possibilities:

  function hello($x) {
     print 'hello ' . $name;
     $x = 1;
  }
 
  function bye($x) {
     if ($x == 1) print 'x = 1';
     else print 'x != 1';
  }
 
  hello($y);
  bye($y);

--------------

  function hello() {
     print 'hello ' . $name;
     $x = 1;
     return $x;
  }
 
  function bye($x) {
     if ($x == 1) print 'x = 1';
     else print 'x != 1';
  }
 
  $y = hello();
  bye($y);

--------------

  function hello() {
  global $x;
     print 'hello ' . $name;
     $x = 1;
  }
 
  function bye() {
  global $x;
     if ($x == 1) print 'x = 1';
     else print 'x != 1';
  }
 
  hello();
  bye();


Cheers!

Mike
