Check which variable reached 100 first!

[Anon]

Yo! I have a really tough problem here that I would like to have solved!

I have three variables in an array:

$num[1] = 0;
$num[2] = 0;
$num[3] = 0;

And three more variables.

$num[1]["add"] = 10;
$num[2]["add"] = 5;
$num[3]["add"] = 2;

the formula I want to use is like this:

$num[$i] = $num[$i] + num[$i]["add"];

And here is the problem: I want to make some sort of loop (probably within another loop) that will check which of the variables ($num[1], $num[2] and $num[3]) was first to reach 100.

IMPORTANT NOTICE: Sometimes I would like more than three variables to change! So the loop must use the expression $num[$i];

Could someone help me with this???

$i=0;
while ($i <= $whatever var):
if ($num[$i] == 100) {
$firstvar = $num[$i];
}
$i++;
endwhile;

echo "First variable to reach 100 was ".$firstvar;

That might be what you want

hmmm i think it could be done easier, but here is something:
<?php
$num[1]["num"] = 0;
$num[2]["num"] = 0;
$num[3]["num"] = 0;
$num[1]["add"] = 10;
$num[2]["add"] = 5;
$num[3]["add"] = 2;
while(1)
{
for($x = 1; $x <= count($num); $x++)
{
$num[$x]["num"] += $num[$x]["add"];
if($num[$x]["num"] >= 100)
{
$z = true;
print('First var that reached 100 was $num['.$x.']');
break;
}
}
if($z == true)
break;
}
?>

You'd need a break/exit in that loop of course to stop all the variables being passed into $firstvar

oops

A minor tweak would be to replace the first "break;" with "break 2;" and then you can dispense with $z, the test on it and that second break.

Gee, why doesn't C have that? 😉
