quck question about Global

phprock

php settings to GLOBAL_OFFS..

is that mean i can't use global variable ?

what is happing i have two file let say config.php and index.php


//config.php 
<?
//config.php 
$siteurl="http://localhost";

?>

<?
//index.php 

include("config.php");
function  site() {

{
global $siteurl ;

echo"Your site is $siteurl";

}
?>

why this above code work when globals_off in php settings..

I am confused.. I used to just include the config.php inside function as i thought when global is set to off I can't use global variable.But why it's working

Any answer will be highly appreciated.. thanks .

Ok firstly. When using register_globals = off

Any variable that is

$var etc but not eg.. $_POST will only be parsed in that file, if however you have a function that requires that variable you'll need to like you did use global to make the variable global in the Function. So if you have included a file it will be parsed the same as the file.

On the other hand you have variables like this
$_POST, $HTTP_POST_VARS which are superglobals, dont get the mixed, they can be used on all pages.

Thank you for the reply. so .. i can do this when register global variable is off.

<?
//db.file
function db_connect()
{
  $result= @mysql_pconnect ("localhost", "root", "XXX");
  if (!$result) {
    return false;
  }
  if (!@mysql_select_db("XXX")) {
    return false;
  }
  return $result;
}


$link=db_connect();

?>

And I can do this ???

<?

//index file 
include("db.php");

function index() 
{
global $link;

$result=msyql_query("select  * from table ",$link);

}

?>

Thanks..
