Question

How should I save the pc’s time (not server time) in a PHP variable?
I tried

$a='<script type="text/javascript"> document.write(Date()) </script>';

without luck

Answer 1

The only way to do that would be to send it to the PHP script via a form or query. All the PHP is executed on the server and sent out to whoever requested it. The PC time would have to be sent back to the server for it to know what it is.

Edit: If you want to just use javascript to show the current PC time you can echo out this in your code:

<script language="javascript">
<!--
  var today = new Date();
  document.write(today);
//-->
</script>

In PHP it would be:

$timeString='

<script language="javascript">
<!--
  var today = new Date();
  document.write(today);
//-->
</script>
';
echo $timeString;

It would show up as Thu Jul 26 2012 00:17:43 GMT+1000 (EST) on the client PC. Here is a link to a decent tutorial on how to use javascript to display dates, times and all sorts of other goodies based on the users PC.

Edit 2: This Javascript will display the date and time nicely.

<script type="text/javascript">
<!--
var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth();
curr_month++;
var curr_year = d.getFullYear();
var curr_hour = d.getHours();
var curr_min = d.getMinutes();
document.write(curr_month + "/" + curr_date + "/" + curr_year + " - " + curr_hour + ":" + curr_min);
//-->
</script>
