Javascript and PHP?

[Lamez]

I have this JS code here:

 

userpick[0]=0;

 

It is just a snippet.

 

How do I set it as a php variable, but it still can be processed as a JS variable?

 

like this maybe?

$a = userpick[0]=0;

You can't, at least not directly. PHP runs on the server, Javascript runs on the client. You can do it if you employ AJAX techniques.

Well how would I do that?

Lamez,

 

I often create 'dynamic' javascript based off a php function. I'm not sure if this is exactly what you're looking for, but you could always generate the javascript code like

<?php

$a = 'userpick[0]=0';
// put straight into string here, but
// could also be done dynamically such
// as $a = 'userpick['.$index.']=0';

?>

 

and then echo that code when needed in your html

 

<script language="JavaScript" type="text/javascript">
<?php echo $a ?>
</script>

 

Maybe this isn't what you're asking for, but if it is, it can be done, the only somewhat tricky part is getting all of your quotation marks to work out correctly.

alright, I will try this, also you forgot a ; when you where showing the JS example

 

lol, I been using PHP for the last 4 or 5 days stright, and I just notice these things now.

Heh, I did forget the ';'. Shows how much javascript I actually write. But like ken said, php is server-side, and javascript is client-side, so anything client side you can technically create dynamically, including javascript. It just takes patience.

That's using PHP to generate Javascript, which isn't what the OP seemed to request.

Semi-colons are optional in javascript.

I agree. Its possible (and even necessary) to output javascript from PHP, so that when its passed from the server to the browser, the javascript is there to be accessed. But its impossible to use javascript in PHP because php is processed on the server and javascript is processed on the browser. The closest you can do is set cookies with javascript and read them with php.

[Lamez]

<script language="JavaScript" type="text/javascript">
<?php echo $a ?>
</script>

 

it should be

 

<script language="JavaScript" type="text/javascript">

<?php echo $a; ?>

</script>

[haku]

That's php, not javascript.

 

That being said, it would have worked without the semi-colon in that case as well.

[Lamez]

oh, never knew that

 

well could I set this as a variable?

 

Wtf, every time I try to post the code I get a 406??

 

here is a link to what I want to set as a variable:

I'm not sure what you are trying to ask.

[Lamez]

sorry, I was getting mad.

 

The link takes you to a text file, and its contents is what I want to set as a PHP variable.

include("file/name.txt");
