Review

Better to use $array[] = to add a new element to an array because it is more efficient according the the PHP docs:

$joinQueries[] = $value[0] . ' JOIN ' . $joinQueryFragment . ' ON ' . $this->generateColumn($value[2]) . ' ' . $value[3] . ' ' . $this->generateColumn($value[4]));
Better to use `$array[] =` to add a new element to an array because it is more efficient according the the [PHP docs](https://www.php.net/manual/en/function.array-push.php): ```php $joinQueries[] = $value[0] . ' JOIN ' . $joinQueryFragment . ' ON ' . $this->generateColumn($value[2]) . ' ' . $value[3] . ' ' . $this->generateColumn($value[4])); ```
