Variables from php to js

[cfgcjm]

I have a PHP variable array that holds info from a database. I need to pass a few variables from the PHP into javascript. Anyone know how to do this?

<?php

echo "<script type=\"text/javascript\">\n";
echo " var jsVariable = $phpVariable;\n";
echo "</script>\n";

?>

If you're looking for "live" interaction back and forth, not just having php set the vars and that's all you need php for, then look into ajax.

Ajax does seem to be worth a look into, but in the meanwhile:

 

<?php
$phpvariable = "foo"; // Or whatever
?>

<script type="text/javascript">
var jsvariable = "<?=$phpvariable?>";
</script>

 

Works for me, but you should use Ajax if you intend to use server stored data in a client side application and then reupload it back to the server, you want to be careful about javascript injections in the address bar and such.
