Bring variables from php to JAVASCRIPT

[Steph]

Hello,

Does someone know how can we bring variables from a PHP script to a
Javascript one ?
I have to build a Javascript function that needs variables generated by a
PHP script but i do not know the way to retrieve them into Javascript.

Many tanks in advance for your help

All the PHP runs on the server, then all the JavaScript runs on the client.
For PHP to send information to JavaScript it has to output JavaScript code.

<script type="text/javascript">
var foo = "<?php echo $foo; ?>";
</script>

For JavaScript to send information to PHP, it has to get the browser to make
a new HTTP request.

document.locati on = "http://www.example.com/myScript.php?fo o=" + foo;

I've made a test and it works.

You might find this project handy for getting Javascript to talk to PHP
over XmlHttpRequest: http://jpspan.sourceforge.net/wiki/doku.php

If you wanted to save a few keystrokes you could
var foo = "<?=$foo; ?>"

Save a few keystroks compared to what? Please quote some context!

That depends on the PHP short tags option being enabled.
