global variables...

1. i understood that one should use global $a,$b;
   in starting of a function if u want to use those variables.
   but after conn_exec i want to store result_id in $resu and to be used in another function

2. i even tried with $GLOBALS["$resu"];
   its not working what to do?

   eg;
   $resu;
   function a()
   { global $resu;
   $resu=exec statment;
   }
   function b()
   {
   gloabal $resu;
   odbc_result($resu,"name");
   odbc_result($GLOBALS["$resu"],"name");
   }
   i try to echo $resu in function b there is nothing

what should i do?

i always use it the following way:

global $test;

function blah() {
global $test;

$test = 4;
}

function print() {
global $test;

echo $test;
}

that way, it works all well.

Globals globals.. what ever happened to parameters?

Try passing your variables to your functions like this:

$my_var="hello";
my_function($my_var);
exit;

function my_function($a)
{
print $a;
};

If you want to also be able to change the content of the variable you pass to your function and have it change for the whole program:

function my_function(&$a)
{
$a="byebye";
};

lovely. no messy globals. 🙂
