You have to think about it this way:

PHP code works with what the server "knows".
Javascript code works with what the browser / client "knows".

To get them to interact, you need to explicitly "pass" information back and forth between the two.

For example, if you have a variable in the javascript, you can "pass" the value to the server by passing it with a GET variable, e.g.

<script language="javascript">
Fuction PassNumber(nVal) {
   location.href = 'mypage.php?n='+nVal;
}
</script>


Then, on the server side, you receive the GET variable to produce the effect that you want:

<?php

$nval = $_GET['n'];
if ($nval)
{
  print('<script>alert('.$nval.');</script>');
}
?>


Contrariwise, when you have the PHP variable on the server side, you can use that to feed it to the Javascript function when rendering your onclick function:

<input type="text" name="text1" value="200" /><br />
<input type="button" value="Go" onClick="PassNumber(this.text1.value+<?php print($nval) ?>)"   />


This requires a re-load of the page, and change of URL, each time you click the button. To do it more "subtley", without a reload, you would have to use AJAX: but the principle would be the same. Pass the information between Server and Browser using calls to the PHP page with GET.
