Use ajax and php as an intermediate :

1. Define an empty JS array :

   var myarray = new Array();

2. use ajax to call your php script, javascript will eval the output by PHP (note this uses prototype library):

    new Ajax.Request('myfile.php', {
   
       onSuccess : function(xmlHTTP) {
   
           eval(mlHTTP.responseText);
       }
   
   });
   

3. Write your PHP code to grab data and print JS code (it must be valid javscript !) :

   $i=0; $q=mysql_query('select ..');
   
   while($row=mysql_fetch_array($q)){               
   
       echo "myarray[".$i."]='".$row['data']."';";
   
       $i++;  
   }
   

4. You can check that your Js array contains data :

   alert(myarray.length); 
   

hope this helps.
