Problems with javascript, pfft!

right i searched google and i can't find ANYTHING that is easy enough for me to understand. I can do php but NOT javascript.

How would i go about setting a php variable as a js object or setting a php session as a js object or w/e

Eg.

PHP Code:

---

<?
$playername = JAVAVARHERE ?>

---

My current code is:

HTML Code:

---

<script type=text/javascript>
function addplayer(id){
");
$xyz = mysql_query("SELECT * FROM `players` WHERE `id`='id'");
$xyzz = mysql_fetch_array($xyz);
echo ("
alert('You have selected'+id);
alert('$xyzz[lastname]');
}
</script>

---

And obv my query is duffage. +rep to all help

You can't. Just echo the data directly into the javascript code.

<?php
include "config.php"; // includes config file

$query = mysql_query("SELECT * FROM table");
$row = mysql_fetch_array($query);
?>
<script type="text/javascript">
alert('<?=$row[thingy];?>');
</script>

One way to do it.
