EN

js_array[0]=a,q,s,t,u;
js_array[1]=a,q,s,t,u;
js_array[2]=a,q,s,t,u;
js_array[3]=a,q,s,t,u;
js_array[4]=a,q,s,t,u;
js_array[5]=a,q,s,t,u;

    $new_array = array(); // create a new array
$sql=mysql_query("SELECT * FROM animate ORDER BY RAND() LIMIT 5") or die("query Field");

 while($row=mysql_fetch_array($sql)){

    $new_array[] = $row['code'];

 }

var array =[<?php echo json_encode($new_array);?>];
        alert(array[0]);
   for(var i=0; i <=9 ; i++)
        {
            array[i]=[<?php echo json_encode($new_array);?>];
    }

array[0]=a;
array[1]=q;
array[2]=s;
array[3]=t;
array[4]=u;
