I just wanted to try this: I take a link : http//www.xy.com/index.php?contents=HOME There I echo contents <?php echo $contents?> <div align="center"><?php echo $contents; ?></div> It should display HOME? But it does not !

Two possibilities I can think of: (1) Is your echo statement above within a function? If so, you have to globalize it, or pass it as a function parameter: function zaphod($beeblebrox) { return '<div align="center">'. $beeblebrox. '</div>'; } echo zaphod($contents); or function zaphod() { global $contents; return '<div align="center">'. $contents. '</div>'; } echo zaphod(); See http://www.php.net/manual/en/language.variables.scope.php for more info. (2) The register_globals parameter is not set. This must be on if you want GET/POST/COOKIE etc. parameters to be automagically converted to variables. This can be set in php.ini, .htaccess, or httpd.conf, and can also be programmatically set and checked via ini_set() and ini_get(), respectively. If this is NOT set, you'll have to refer to your GET parameter as $HTTP_GET_VARS['contents'] See http://www.php.net/manual/en/configuration.php http://www.php.net/manual/en/language.variables.external.php http://www.php.net/manual/en/function.ini-set.php http://www.php.net/manual/en/function.ini-get.php for more info. - steve

anyone has an idea why not?
