Usage

$parser = new \PHPFUI\MySQLSlowQuery\Parser($logFilePath);

// Return the sessions in the file as array
$sessions = $parser->getSessions();

// Return all entries in file as array, or pass session number (0 based)
$entries = $parser->getEntries();

if (count($entries))
  {
  // Get the worst offender
  $entry = $parser->sortEntries()->getEntries()[0];
  echo 'Query ' . implode(' ', $entry->Query) . " took {$entry->Query_time} seconds at {$entry->Time}\n";

  // Get the most rows examined
  $entry = $parser->sortEntries('Rows_examined', 'desc')->getEntries()[0];
  echo 'Query ' . implode(' ', $entry->Query) . " looked at {$entry->Rows_examined} rows\n";
  }

Sort Entries

By default, entries are returned in log order, but call sortEntries on the Parser to sort by any valid field (parameter 1). Sort defaults to 'desc', anything else will sort ascending.
