[Solved] How can we get value in php variable from javascript variable

by


PHP is processed on the server, before sending the result to the client.

For example, if you do this:

<p>
<?php
$name = "Dan";
print "hello, $name, ";
?>
How are you?
</p>

The client will get:

<p>hello, Dan, How are you?</p>

And then, the client will process any javascript included in the code.

So in your case, the server would try to process this code:

<?php $n ?>

and then send the result to the server, appending the code out of the tags. Which would give an error, since $n by itself is not a valid php instruction.

So: PHP is executed on the server, and then, javascript is executed on the client.

You should check some tutorials, and try first to understand how PHP and Javascript work.
