TalkPHP - View Single Post - When was the last time you used the global construct?

If you remember, the global construct allows you to bring in variables to use in a function that didn't declare them. Like so:

php Code:

$iX = 2;
$iY = 3;

function multiply()
{
    global $iX, $iY;
    return $iX * $iY;
}

echo 'Total: ' . multiply();

However, I really cannot remember the last time I used that in any of my scripts - thanks to OOP! How about everybody else?

If you remember, the `global` construct allows you to bring in variables to use in a function that didn't declare them. Like so: php Code: $iX = 2; $iY = 3; function multiply() { global $iX, $iY; return $iX * $iY; } echo 'Total: ' . multiply(); However, I really cannot remember the last time I used that in any of my scripts - thanks to OOP!
