Hello PHP gurus,

I start learning PHP a couple of days ago. I am running PHP 4. on Red Hat 9.
Look like things are setup correct. I have no problem running since script
like
<?
phpinfo();
?>.

However, I can't get the any variable output from the following, whether
clicking on the "Test" or not. $QUERY_STRING, $Year, and $Month are always
empty.

File test1/php:

<html>
<head>
<title></title>
</head><body>
<?
echo "QUERY_STRING = $QUERY_STRING <br>\n";
echo "Year = $Year<br>\n";
echo "Month = $Month<br>\n";
echo "<a href=\"./test1.php?Year=2005&Month=1\">Test</a>";
?>
</body></html>

Please help. Thanks a bunch.

You should avoid short open tags (may be disabled on the server and may
cause problems with XML). Use <?php ... ?> instead for portable code.

In recent PHP versions register_globals is turned off, that's why these
variables no longer exist.

Chapter 28. Using Register Globals
http://www.php.net/manual/en/security.globals.php

Use the superglobal arrays $_SERVER, $_GET etc. to access their values:

$_SERVER['QUERY_STRING']
$_GET['Year']
....

Thanks. That works. Apparently, the manual I got is too old.
