Hi, all.
I'm just wondering why a variable defined within a function is not available
as a global to functions called from the same scope. There's probably a
really good reason for this, but I'm not sure I know what it is.
Feel free to educate me.
Ta muchly,
JP.
--- Code example follows ---
<?PHP
// Simple global variable scope test.
Function startTests()
{
$G_test = "Hello, World.";
globalTest();
}
Function globalTest()
{
global $G_test;
if (isset($G_test))
{
echo ("Global variable 'test' - value:
'<B>".$G_test."</B>'.<P>\n");
}
else echo ("Global variable 'test' is not set.<P>\n");
}
?>
