Insert Custom Options of product with script - php

Question

I have a script for inserting a product custom options in Magento. Its working fine for single custom option, if there are multiple custom options for a single product then it insert only single custom option and discard others.
<?php
// Report all PHP errors (see changelog)
error_reporting(E_ALL);
ini_set("display_errors", 1);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
// Include Magento application
require_once ( "../app/Mage.php" );
umask(0);
// Initialize Magento
Mage::app("default");
$start = 0;
$totalno =1000;
$row = 0;
$sku = 0;
$baseRowoption = array();
$myarrayoption = array();
if (($handle = fopen("custom_option-final.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle,",")) !== FALSE) {
$num = count($data);
for ($c=0; $c < $num; $c++) {
if($row == 0){
$baseRowoption[$c]=$data[$c];
}else{
if($c==0){
$sku=$data[$c];
}
$myarrayoption[$sku][$row][$baseRowoption[$c]]=$data[$c];
}
}
$row++;
if($row > $totalno){
break;
}
}
fclose($handle);
}
$myarrayoptionfinal = array();
foreach($myarrayoption as $key=>$myarrayoption1){
//if($key != "smartek-rx3044"){ break; }
