How I can do this PHP If Statement in right way? - php

Question

I have 50 variables in php. I want to check each of them and if they true then add 2 points in a variable called $point. I am new so I write a few lines but I think I am doing wrong way.
$strenght_point = 0;
if($f_name){$strenght_point++;}
if($l_name){$strenght_point + 2;}
if($full_name){$strenght_point + 2;}
How can I do it right way.Thanks
Update my full function is here...
It's Codeigniter Controller Function
Hope you guys understand well now
function strength_scale() {
$user_id = $this->uri->segment(2);
$user_name = $this->uri->segment(3);
$query = $this->db->get_where('aoa_user', array('id' => $user_id, 'username' => $user_name));
foreach ($query->result() as $row){
$f_name = $row->f_name;
$l_name = $row->l_name;
$full_name = $row->full_name;
$username = $row->username;
$alias_name = $row->alias_name;
$gender = $row->gender;
$country = $row->country;
$avatar = $row->avatar;
$cover_photo = $row->cover_photo;
$email = $row->email;
$skill = $row->skill;
$other_skills = $row->other_skills;
$ex_time = $row->ex_time;
$about = $row->about;
$company = $row->company;
$company_position = $row->company_position;
$phone = $row->phone;
$facebook = $row->facebook;
$facebook_page = $row->facebook_page;
$google_plus = $row->google_plus;
$twitter = $row->twitter;
$youtube = $row->youtube;
$skype = $row->skype;
$linkedin = $row->linkedin;
$website = $row->website;
$latitude = $row->latitude;
$longitude = $row->longitude;
$verification = $row->verification;
}
$strength_point = 0;
if($f_name){$strength_point++;}
if($l_name){$strength_point + 2;}
if($full_name){$strength_point + 2;}
}

Answer 1

Create an array with the variables instead.
https://3v4l.org/FYTtG
$arr = array("f_name" => true, "l_name" => true, "full_name" => true);
$strength=0;
Foreach($arr as $var){
if($var) $strength = $strength+2;
}
Echo $strength;

Answer 2

As Rizier123 said, you need to increment your strength variable correcly.
You could write a simple function that would accept one of your 50 variables and return the strength increment:
function defineStrength($param)
{
if ($param) {
return 2;
}
return 0;
}
$strength = 0;
$f_name = true;
$l_name = false;
$full_name = false;
$strength += defineStrength($f_name);
$strength += defineStrength($l_name);
$strength += defineStrength($full_name);
However, an array would be a better way to go, as Andreas mentionned.
In your question update you said you use CodeIgniter. As the documentation states you can return the query result as a pure array.
So you could further develop like that :
function defineStrengthFromArray(array $row)
{
$strength = 0;
foreach ($row as $param) {
$strength += defineStrength($param);
}
return $strength;
}
foreach ($query->result_array() as $row){
$strength = defineStrengthFromArray($row);
}
