PHP Injection Attack?

I'm getting a connection reset on my local computer and these messages in the Apache log:

This is from a snippet I got from this site:

// Database size = table size + index size:
  $rows = db_query("SHOW TABLE STATUS");
  $dbssize = 0;
  while ($row = mysql_fetch_array($rows)) {
    $dbssize += $row['Data_length'] + $row['Index_length'];
   }
  $output = "$dbssize bytes<br />";
  $dbssize = db_size_info($dbssize);
  $output .= "or<br />" . "{$dbssize['size']} {$dbssize['type']}";
  print $output;


function db_size_scale($dbsize) {
  $bytes = array('KB', 'KB', 'MB', 'GB', 'TB'); 
  if ($dbsize < 1024) $dbsize = 1;             
  for ($i = 0; $dbsize > 1024; $i++) $dbsize /= 1024;
    $db_size_info['size'] = ceil($dbsize);
    $db_size_info['type'] = $bytes[$i];
    return $db_size_info;
}
