WampServer

I've installed WAMP 2.2e (Apache 2.2.22), php5.4.3, & mysql 5.5.24-32 on a new Windows 7 Home Premium PC.
On our previous Windows Vista PC, I had been successfully executing Apache 2.2.10, php 5.2.6, and mysql 5.1.30.
After the WAMP installation on the Windows 7 PC,
the WAMP server icon is green,
I launched Localhost from the WAMP server icon, & a meaningful page is displayed & the phpinfo() choice returns much meaningful data,
thru phpmyadmin, I've imported a database & the phpmyadmin browsing function seems accurate,
I've executed the simple "hello.php" module, & it worked OK -- however, I changed the simple php code to:
<?php echo '<p>Hello World.</p>'; phpinfo();?>,
-- after executing this small change, the FF browser displays the "Hello..." message, followed by ';phpinfo(); ?>
I've tried other "simple" php code changes, but the php code is not being recognized.
Should I downgrade to a previous php version?
Thank you.

I tried your piece of code it's working perfectly.

I removed the , at the end of your line of code... is that causing your problems?


It prints hello world, followed by the server php settings screen.....

Chihwahli, thank you for the response. The comma following phpinfo();?> is not in the php module. I feel as if the issue is a simple one, but I haven't resolved it yet.
