Making a variable variable. :)

[thepez]

I'm trying to make a variable variable if that makes sense? eg. I have a loop that will add a number to a variable that will be used in an IF statement:

while(c<=3) {
c++;
$varname = "thevar".$c;

if($varname==1) {
... blah blah blah ...
}

}

I want the IF statement to grab the actual value of the variables that were named (eg. $thevar1, $thevar2, $thevar3).

I'm assuming I use some kind of Evaluate function?

Couple ways:

$varname = "thevar".$c;
$$varname = 'value';
echo $$varname;

OR

${'thevar'.$c} = 'value';
echo ${'thevar'.$c};

How 'bout something like:

// clean up that little while(c <= 3) in your post and make it $c so it doesn't throw a parse error.
while($c <= 3) {
	switch($c) {
		case 0:
			// blah
		break;
		case 1:
			// blah blah
		break;
		case 2:
			// blah blah blah
		break;
		case 3:
			// blah blah blah blah
		break;
	}
	$c++;
}

This, of course, assumes that '3' is constant...
