if
global $var;
is called from within a function and $var exist outside the nested function
then the $var will be available to the function.
example
$var = "hello world";
function say_hello() {
global $var;
echo $var;
}
will echo "hello world"
while
$var = "hello world";
function say_hello() {
echo $var;
}
wont echo "hello world"

Subject: [PHP] session and global
Hi folks
I just wonder as I saw someone useing session with global and some don't.
What is the reason to use session together with global?
Like this:
session_start();
global $test
session_register('test');
I look up in manual using keyword "global", but could not find anything near
this.
Jack
