variable scope?!?

[Anon]

Somebody please help me!

Why does this not work?

<?
$on = "<b>ON</b>";
$off = "<b>OFF</b>";
$template = "$state - $i - hello<br>";

$i = 1;
while($i <= 20) {
	if ($i % "2") { $state = "$on";} 
	else { $state = "$off"; }
	echo "$template";
	$i++;
}

?>

I want the variable in "$template" to get filled by the prcoessing of the while and if... but it don't!

Much appreciate any help! 🙂

thx.

By the time you set the state variable you have already built the template variable what you need to do is change you code to

<?
$on = "ON";
$off = "OFF";

$i = 1;
while($i <= 20)
{
if ($i % "2")
{
$state = "$on";
}
else
{
$state = "$off";
}
$template = "$state - $i - hello<br>";
echo "$template";
$i++;
}

?>

Mark.

Or even more logical:

echo $state." - $i - hello<br>";

and even better:

echo $state.' - '.$i.' - hello<br>';

becuase you should never ever quote variables.
