Show Present time in page

If you mean a 'clock' which shows the current time without refreshing the page, PHP is not the place for you, try looking for Javascript clocks.

Thank you for your reply.
please write the javascript code for Clock

Thanks in advance.

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

But, seriously, how about you do some searching, try to put something together and when you have problems you post what you have so far and we provide you with some assistance.

There is a nice JS clock tutorial in this link:

I hope it would have good use for you.

Cheers,
