how can I run for loop 4 times

I have an array that I have counted and it equals 4. That is what it should equal. Now I want the foreach loop inside the for loop to only run 4 times. As it stands, I am getting to many results. Below is my latest attempt that does not work. 

    $networks = array();
    $networks = ! empty( $instance['networks']) ? $instance['networks'] : '';
    $size = count($networks); //size equals 4

    for($i = 0; $i <= $size; $i++){
        foreach ( $this->networks as $key => $value ) {
            $network_names[ $key ] = $value['class'];
        }
     $i++;
    }

the networks array is populated from a WordPress widget that has a repeating field section. The section allows the user to set social media icons. I currently have 4 social media icons set. On the front end, the page shows every social media icon available even though there are only 4 set. So I am trying to get the nested foreach loop to only run 4 times.

I have something more interesting for you.. it's a widget parent with children! You can change field to load new fields from other classes here's the link:

Currently your loop is executing 5 times..and you want it to run only 4 times... So Change this condition...for($i = 0; $i <= $size; $i++) to either for($i = 0; $i <$size; $i++) or for($i = 1; $i <= $size; $i++) like i.e.

$networks = array();
$networks = ! empty( $instance['networks']) ? $instance['networks'] : '';
$size = count($networks); //size equals 4

for($i = 0; $i < $size; $i++){
    foreach ( $this->networks as $key => $value ) {
        $network_names[ $key ] = $value['class'];
    }
}
