Javascript function which pass parameter into a php function. My javascript code is below

```
function add_card(card_listt,card_number){  
   var card = card_listt;
   var num = card_number;
   //document.write(card+num);
   for (var i = 0; i < num; i++) {
      var avrl = "http://192.168.27.123/?Command=add:"+card[i]+","; 
      document.write('<?php get_data($avrl); ?>'); // Here is Problem
      document.write('<?php add(1,2); ?>'); //It works fine If I use  
   }
}

```

my php function is below. when I use only `document.write('<?php add(1,2);?>');` function then it works properly. But when I use `document.write('<?php get_data($avrl); ?>');` function then it does not works.

```
<?php

    function get_data($url) {
       $curl_handle=curl_init();
       $timeout = 20;
       curl_setopt($curl_handle, CURLOPT_URL,$url);
       curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
       curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt($curl_handle, CURLOPT_USERAGENT, 'Welcome');
       $data = curl_exec($curl_handle);
       //return $data;
       echo $data;
   }

   function add($a,$b){
      $c = $a + $b;
      echo $c;
   }

?>
