Question

I got really confused when i tried to transfer variables from php to js.
everything is fine when i try to get value using an id
for example:

var name = $("#name").val();

but my question is, if i want to convert for example this variable:

$id = 182938; //the id of the user

to this variable:

var id;

this question might be dumb… maybe easy for you, but not for me :p
I have looked it up and only found something like this anywhere i looked for:

<?php
$number = rand();
?>

<script language="javascript">
var num = <?php echo $number ?>
</script>

Does it have the same affect as passing down the value?

Thanks!!

Not quite. Encoding as JSON will ensure that it is a valid JavaScript literal.

var num = <?php echo json_encode($number) ?>
