Understanding fetch_assoc()

Question

I am trying to understand how/why fetch_assoc works the way it does. I have the following piece of code:

$results = $connectToDb->fetch(\"SELECT * FROM cust         


        

Answer 1

I think it useful:

function get_posts(){
$posts = array();
if ($result = $mysqli->query("SELECT  id, post_userid, name, lang, country, post_image, post_date, post_date_updated FROM posts ORDER BY `post_date` DESC ;")) {

    while ($row = $result->fetch_assoc())
    {
        $posts[$row['id']] = $row ;   
    }
} else {
    printf("Prepared Statement Error: %s\n", $mysqli->error);
}
return $posts;

}
