Running PHP code from javascript

[Jacob or JaF]

How can I run PHP code from javascript?

You can't for the most part(javascript=client-side, PHP=server-side..there must be some link). What are you trying to do? Maybe there is an alternative.

If you want to change your javascript using PHP, you can load the js content on your .php page and change the data dynamically. But, yep, what are you trying to do?

You can (call a PHP script in a JavaScript "script" tag) , as long as the PHP script returns JavaScript code.

One easy method/use is for inserting/embedding text or HTML -- the PHP would just return a JavaScript document.write() command.

// You may need to add a content-type header:
 header("Content-type: application/x-javascript");
// This must be done before the script outputs any data.
$output_string="Hello There<br>";
echo "document.write('" . $output_string . "');";
/*
The script would be called within a <script src="script.php"></script> object and it can return any JavaScript code you like.
*/

You can also return images, and other dynamic content this way --
