loop through php within Javascript

I am running a javascript file either on my hard drive or from my website, right now, I have been trying to get this to work from my hard drive. The javascript loops through and builds a table with x number of rows. Each row has a "textarea" box where users can type in mutual funds ticker symbols. I would like to populate the textarea boxes with data from a mysql database. From the advice I got f开发者_运维问答rom Will, I am using a PHP file to return JSON, but I can't figure out how to iterate through the JSON and put one fund symbol in each row of my javascript table.

below is my php file on my website

<?php
$connect = >>>>>my connection string here<<<<<;
mysql_select_db("altatech_grid");
$result = mysql_query("SELECT FSymbol FROM FundSymbols"); 
$to_encode = array(); 
while($row = mysql_fetch_assoc($result)) {
  $to_encode[] = $row['FSymbol'];
} 
$myFund = json_encode($to_encode);
echo ($myFund);
?> 

which returns this below <<<<<<

["FDGRX","FVINX","VCVLX","LLPFX "]

this is my javascript below <<<<<<<

document.write("<table>");
nButtons = 0;
for (row = 1; row < nItems; row++)
{
document.write("<tr>");
for (rowButton = 0; rowButton < row; rowButton++)
document.write("<td><textarea class='unorderedlist' wrap='soft' name='possibility" + (row+1) + "' id='p" + (row+1) + "'>")";
########### This Is Where The PHP Needs To Put One Item In Each Row ############
document.write("</textarea></td>");
document.write("</tr>");
document.write("</table>");
}

This isn't JSON, it's an array...

var i;
var html = "<textarea>";
var symbols = ["FDGRX","FVINX","VCVLX","LLPFX"];
for (i = 0; i < symbols.length; i++) {
    html += symbols[i] + "\r\n";
}
var html += "</textarea>";
document.write(html);

JSON objects look like this:

var jsonObject = { name: "John", location: "UK" };

And you could add your dynamic values like this:

var symbols = <?php echo $myFund; ?>;

I think that there is no way to do like you want. Because, PHP is script run at server. So you could not run a PHP script from client using Javascript. But you can do like below:

<script type="text/javascript">
    var data = <?php echo json_encode($to_encode);?>;
    //At client it will be:
    //var data = ["FDGRX","FVINX","VCVLX","LLPFX"];
    //Then you can loop:
    for(var row = 0; row < data.length; row++)
    {
        //@Todo
        //.................
        document.write(data[row]);
    }
</script>
