[PHP] Re: scope problem

[Andre Cerqueira]

can you post something that would run on php?

Apparently I'm having some kind of meltdown here.  Can anyone explain the
logic behind why the following variable has the original value and how I can
pull/push the value to access it at the end?

while loop
{
        $variable = 100;
        while loop
        {
                switch($othervar)
                {
                        case 1:
                                $variable = $variable + 100;
                                break;
                        case 2:
                                $variable = $variable + 200;
                                break;
                        case 3:
                                $variable = $variable + 300;
                                break;
                }
                echo $variable."<br>";
        }
        echo "<br>The final value is ".$variable."<br>";
}

This gives values something to the tune of...

200
400
700

100

I usually have variables set outside of a while loop that increment based on
the contents of the loop and I could swear that they hold the value on the
other side of the loop.  I don't usually use break; in my scripts unless I'm
using switch. However, I would think that if using break was throwing me,
that the value wouldn't print on each cycle of the loop.

TIA
