I need a little bit of help im trying to page a js variable into a url thats being parsed in php using file_get_contents. Im not sure where to start to do that.
<script type="text/javascript">
var js_variable = appl+goog+fb+mfst+nflx;
</script>
<?php
$ticker = js_varable_here;
$file = file_get_contents('.csv?s=$ticker&f=soac1p2ghjkj1re');
?>
any advice is appreciated, like i said im in the dark on this one.

php runs on server and js resides at client. First it gets to server and than to client. You cant pass like that. You can use

- is the js_variable set in your source code (which is what is in your example) or is it set on the client side (a more likely use case)? – Aerik Commented May 25, 2012 at 22:11

Reset to default 2Here's an example using jquery.
Javascript:
<script type="text/javascript">
var js_variable = appl+goog+fb+mfst+nflx;
$.post("/somephp.php", {ticker: js_variable}, function(data) {
// returned from php
});
</script>
PHP:
<?php
$ticker = $_POST['ticker'];
$file = file_get_contents("http://finance.yahoo./d/quotes.csv?s=$ticker&f=soac1p2ghjkj1re");
?>
Expanding on what Jashwant says...
PHP is a server-sided language, which does work behind the scenes. Javascript is client-side, which runs and executes code on the local client's machine (ie through the browser).
You can however use AJAX (Asynchronous JavaScript and XML) so the local client sends HTTP requests to the server without reloading the current page. For instance, you can use AJAX to send the contents of the variable to the server.
For easier usage, you should check out jQuery's methods regarding ajax calls. See: http://api.jquery./jQuery.ajax/
Hope it works well.
Heres how you can do it with jquerys post() and then return json, you could build the result as you expect to output within the php part or you could use jquery to loop with each() through the result.
<?php
if($_SERVER['REQUEST_METHOD']=='POST'
&& isset($_SERVER['HTTP_X_REQUESTED_WITH'])
&& strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) === 'xmlhttprequest'){
if(!empty($_POST['s'])){
$ticker = $_POST['s'];
$file = file_get_contents('http://finance.yahoo./d/quotes.csv?s='.$ticker.'&f=soac1p2ghjkj1re');
header('Content-Type: application/json');
echo json_encode(array('result'=>$file));
}else{
echo 'Request not allowed!';
}
die;
}
?>
