Please consider the following scenario with a simple HTML document and a JavaScript loaded in it:
<!-- doc.html -->
<!doctype html>
<html lang="en">
<head>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script type="text/javascript" src="script.js"></script>
</head>
</html>
// script.js
window.onload = function()
{
var d = new Date();
d.setHours(<?php echo(date("H")); ?>);
}
It's really Quite simple, isn't it? However, while this coode works perfectly for getting the current hour (which will be returned as an INT), it doesn't if I try to receive a more complex date/time format like the one below:
var serverTime = <?php echo date("Y-m-d H:i:s"); ?>;
This should encode to 1900-01-01 00:00:00. So, cause this is not a legal expression I want to encapsulate the result with quotes:
var serverTime = "<?php echo date("Y-m-d H:i:s"); ?>";
At a first glance this should work. Unfortunately, it doesn't. serverTime contains just an empty string.
What am I doing wrong?
Maybe your Timezone isnt correctly setup
try
<?
date_default_timezone_set('America/Los_Angeles');
?>
or similar - full list can be found here
Try using single quotes:
var serverTime = '<?php echo date("Y-m-d H:i:s"); ?>';
There is no reason why var serverTime = "<?php echo date("Y-m-d H:i:s"); ?>"; shouldn't return something like:
var serverTime = "2011-05-12 05:12:56";
Check to make sure that echo date("Y-m-d H:i:s"); is working correctly.
Other than that, the code should work fine.

Because you are using double quotes in your JavaScript you need to use single quotes in your php.
var serverTime = "<?php echo date('Y-m-d H:i:s'); ?>";
The javascript won't execute your php code. Think of it like this: When the page is rendered php "replaces your php code" with the output of the php code.
So basically this
var serverTime = '<?php echo date("Y-m-d H:i:s"); ?>';
Should be rendered as
var serverTime = '2011-11-28 xx:xx:xx';
I think you are wrong in the way of you insert your parameters. Acording to this I think you should do this:
// script.js
window.onload = function()
{
var d = new Date('<?php echo(date("F d, Y H:i:s")); ?>');
d.setHours(<?php echo(date("H")); ?>, <?php echo(date("i")); ?>, <?php echo(date("s")); ?>);
}
The statment var d = new Date('<?php echo(date("F d, Y H:i:s")); ?>'); is to follow the example of this link.
Because I can't see why php will fail to send the result of the date() function.
