First Need to get all plans & check with your values.

<?php
$recurring_duration  = $_POST['recurring_duration'];
$planname = "plan value";
$last_customer = NULL;
while (true) {
    $plan_list = \Stripe\Plan::all(array("limit" => 100, "starting_after" => $last_plan));
    foreach ($plan_list->autoPagingIterator() as $plan) {
        if ($plan->id == $planname) {
            $planlookfor = $plan;
            break 2;
        }
    }
    if (!$plan->has_more) {
        break;
    }
    $last_plan = end($plan_list->data);
}

if(!empty($recurring_duration)){
    if(isset($planlookfor) && $planlookfor->id==$planname){

    }else{
        $plan = \Stripe\Plan::create(array(
            "name" => 'Basic Plan'.' '.$recurring_duration_text.' '.$amount/100,
            "id" => $planname,    
            "interval" => "$recurring_duration",
            "currency" => strtolower($currency),
            "amount" => $amount,
        ));
    }
}
