Why are we saying SLUG = FALSE?

1. http://php.net/manual/en/functions.argum...ts.default
A function/method may define default values for arguments, in this case, the default value of $slug is FALSE. If you call get_news() without supplying an argument, $slug will be FALSE.

2. http://php.net/manual/en/function.return.php
Since the last statement inside the curly braces for the if statement is

Code:

return $query->result_array();

, nothing outside the curly braces will be executed if $slug === FALSE

3. Yes, unless you change the code outside the curly braces to change the return type and only set the where clause when $slug !== FALSE. For example:

PHP Code:

public function get_news($slug = FALSE)
{
    $returnMethod = 'result_array';
    if ($slug !== FALSE) {
        $this->db->where('slug', $slug);
        $returnMethod = 'row_array';
    }
    
    $query = $this->db->get('news');
    return $query->{$returnMethod}();
} 


Since this is probably more confusing than the original code, you're probably better off with what you already have.
