如果是else语句的数组

Question

I'm currently hand coding my if else statement

if ($user_location[0] == $location){
        $user_id = $page[0];
    } else if ($user_location[1] == $location){
        $user_id = $page[1];
    } else if ($user_location[2] == $location){
        $user_id = $page[2];
    } else if ($user_location[3] == $location){
        $user_id = $page[3];
    } else if ($user_location[4] == $location){
        $user_id = $page[4];
    } else if ($user_location[5] == $location){
        $user_id = $page[5];
    } else if ($user_location[6] == $location){
        $user_id = $page[6];
    } else if ($user_location[7] == $location){
        $user_id = $page[7];
    } else if ($user_location[8] == $location){
        $user_id = $page[8];
    } else {
        $user_id = $user_gen;
    }

How do I make this if statement that auto increment the $user_location[] and $page[] instead of hand coding?

Try this:

I assume you are using PHP as per you tag your question in PHP

$flag = true;
foreach($user_location as $index=>$each){
    if ($each == $location){
        $flag = false;
        $user_id = $page[$index];
    }
}
if ($flag){
    $user_id = $user_gen;
}
