Summerize all fields if exists from database - php

Question

I have different fields in the database and im fetching their values.
Now what I would like to do is subract a number if certain field exists in database.
Here is my code:
<?php
$percent_profile_image = 40;
$percent_cover_image = 20;
$percent_profiletext = 10;
$percent_travelintext = 10;
$percent_sparetimetext = 10;
$percent_gouttext = 10;
$avatar_status_num;
$cover_status_num;
$profiletext = $display_profile['profile_text_approved'];
$sparetimetext = $display_profile['spare_time_text_approved'];
$travelintext = $display_profile['traveling_text_approved'];
$gouttext = $display_profile['go_out_text_approved'];
if($avatar_status_num == 2) { echo $percent_profile_image; } + if($avatar_status_num == 2) { echo $percent_profile_image; }
?>
Now I know my if code is wrong. What I would like to do if example $avatar_status_num = 2 i would like to print out 40. if $cover_status_num = 2 I would like to substract these to numbers so. 40 + 20. So it should only print out the number and substract it if the value from DB is nr2.
I hope you understand my question :)

Use an extra variable to sum your values.
$sum = 0;
if (isset($someValue) && $someValue == 2) {
$sum += 40;
}
if (isset($someOtherValue) && $someOtherValue == 2) {
$sum += 20;
}
Or if you wanna do this dynamically in your code:
$percent = array(
'profile_image' => 40,
'cover_image' => 20,
'profile_text_approved' => 10,
'traveling_text_approved' => 10,
'spare_time_text_approved' => 10,
'go_out_text_approved' => 10,
);
$sum = 0;
foreach ($display_profile as $key => $value) {
if (array_key_exists($key, $percent) && $value == 2) {
$sum += $percent[$key];
}
}
Note In this case the $percent key names should be the same as the $display_profile key names.
