  True.  But take the following function: 

  function processLotsOfFormVars() { 
    global $fieldOne, $fieldTwo, $fieldThree, $fieldFour; 
    global $fieldFive, $fieldSix, $fieldSeven; 
    global $PHP_SELF, $REQUEST_URI; 
    global $HTTP_REFERER; 

    echo "Field One is: $fieldOne<br>\n"; 
    echo "Field Two is: $fieldTwo<br>\n"; 
  // etc 
  } 

  OR you can do it this way: 

  function processLotsOfFormVars() { 
    echo "Field One is: $GLOBALS[fieldOne]<br>\n"; 
    echo "Field Two is: $GLOBALS[fieldTwo]<br>\n"; 
  // etc 
  } 

  I've done it both ways.  I'm not advocating using 
  "$GLOBALS[var_name];" over "global $var_name", 
  just that it is an alternative if you are using alot of global 
  variables in a function.  Plus, if the function gets large, 
  it's easier to see where the value is coming from by using 
  the $GLOBALS variable. 
  That's all I was saying.
