How to add php content or variable inside javascript alert box?! javascript, php, alertbox

How can i add php content or php variable inside Java-script alert box?!
I tried to make it work few ways but it is only popping up a blank box rather than the contents of php variable.

Here is the code:

<script language="javascript">
$(document).ready(function() {
$("#a").blur(function() {
<?php $b = $_POST['a'];

if(isset($_POST['update'])) {
mysql_query("UPDATE tbl_travel set fld_a='".$_POST[$b]."' where fld_id = '".$_POST["id"]."' ") or die(mysql_error());
} ?>

alert (<?php $b ?>);
});
});
</script>


Thank You for your Help :)

Answer

Change this

alert (<?php $b ?>);

to this

alert ('<?php echo $b; ?>');

You need to output the value of $b and add quotes inside the alert.

About PHP - echo
