Variables and empy() function

[Anon]

Hi, I having a small problem. Please email me [e-mail]

I have variable $move0 $move1 $move2. and $j=0;
I want to check them in an loop to find out if $move0, $move1, $move2 are empty.

I want to use the fellowing empty($move$j) to get access to $move0 variable.
but for some reason it doesn't work;

Shouldn't the following to be equal $move$j and $move$j.

Thanks for the help.

Here is my small code:

$move0="OK";
$move1="OK";
$move2="OK";

$j=0;

while(!empty($move$j)) // this line gives me error message.
{
echo("<br> $j");
j++;
}

// Thank You for your help

You need to use a variable variable, it's constructed like this:

$j = 0;
$variable_name = "move$j";
$$variable_name will now be the same as $move0
