Putting () around ternary's is a "best practise". <?php echo 'Are we ready to go? ', isset($go) ? 'Yes we are.' : 'No we are not.', ' Ready state completed', PHP_EOL; $go = true; echo 'Are we ready to go? ', isset($go) ? 'Yes we are.' : 'No we are not.', ' Ready state completed', PHP_EOL; ?> vs. <?php echo 'Are we ready to go? ' . isset($go) ? 'Yes we are.' : 'No we are not.' . ' Ready state completed' . PHP_EOL; $go = true; echo 'Are we ready to go? ' . isset($go) ? 'Yes we are.' : 'No we are not.' . ' Ready state completed' . PHP_EOL; ?> vs. <?php echo 'Are we ready to go? ' . (isset($go) ? 'Yes we are.' : 'No we are not.') . ' Ready state completed' . PHP_EOL; $go = true; echo 'Are we ready to go? ' . (isset($go) ? 'Yes we are.' : 'No we are not.') . ' Ready state completed' . PHP_EOL; ?> Don't run them just yet.
