100% failure on $GLOBALS, even $GLOBALS['errorArray'] never even 
CREATED!!!!

function &setErrorArray($additionalErrorArray = '') {
  static $errorArray = array();
  print_r("additionalErrorArray = "); print_r($additionalErrorArray); 
print_r(" is array? "); print_r(sizeof($additionalErrorArray)); 
print_r("<P>");
  if (is_array($additionalErrorArray)) $errorArray += $additionalErrorArray;
  print_r("errorArray = "); print_r($errorArray); print_r("<P>");
  if (!isset($GLOBALS['errorArray'])) $GLOBALS['errorArray'] = $errorArray;
  print_r("GLOBALS['errorArray'] = "); print_r($GLOBALS['errorArray']); 
print_r("<P>");
 }

Here is a sample of the output:

additionalErrorArray = Array ( [willSelectFileArray] => Could not locate 
backup file ) is array? 0
errorArray = Array ( [willSelectFileArray] => Could not locate backup file)
GLOBALS['errorArray'] = Array ( )

MySQL training will be coming soon, and in fact, we plan to have a
