Bug Best Practice introduced by
The expression $events of type Drupal\mongodb_watchdog\...godb_watchdog\Event[][] is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

Unused Code introduced by
The assignment to $template is unused. Consider omitting it like so list($first,,$third).

This checks looks for assignemnts to variables using the list(...) function, where not all assigned variables are subsequently used.

Consider the following code example.

<?php

function returnThreeValues() {
    return array('a', 'b', 'c');
}

list($a, $b, $c) = returnThreeValues();

print $a . " - " . $c;

Only the variables $a and $c are used. There was no need to assign $b.

Instead, the list call could have been.

list($a,, $c) = returnThreeValues();
