Answer 1

Why would you use so much '\' ? and what the asterisks '*' after total() for? I have tried following snippet and it seems to works well. (only changing the echo line in your php code)

echo "\t

            ".filter_var($event['eventTitle'], FILTER_SANITIZE_SPECIAL_CHARS)."
            {$event['eventStartDate']}
            {$event['eventEndDate']}
            {$event['catDesc']}
            {$event['venueName']}
            {$event['eventPrice']}
            
      
\n";
