I have this:
a = 23;
function level1()
{$a = 29;level2();echo "<p>".$a."</p>";
}
function level2()
{global $a;echo "<p>".$a."</p>";
}
level1();
echo("Hello, World!" );
?>
The "global" makes $a take on the value of 23, whereas i really need to get it to take on the value of 29.
Clearly this is a simple example of a problem i have which is more complex! |
