[RESOLVED] concatinating to make a variable?

[DKY]

Is there a way to concatenate to make a variable? For example, I have a loop that looks like so:

$j=1;
while($j <10 ){ 
$VarNum="This is the value of variable number ".$j."<br>";
$j++;
}

and I want the variable to increase in number so that I would have $VarNum1, $VarNum2, $VarNum3, etc.... I was thinking I would do something like this

$VarNum.$j="This is the value of variable number ".$j."<br>";

but that doesn't seem to work. Any suggestions?

Ah, so you want variable variables 😉

Youd' need something like this:

$base = 'VarNum';

for($i=0; $i<10; $i++)
{
    $varName = $base.$i; // Holds the string "VarNum1" ... "VarNum9"
    $$varName = 'This happens to be a variable .... dynamically generated with the number: ' . $i;
}

echo $VarNum1.'<br />'.$VarNum2;

Hope that helps.

My first suggestion would be to use an array instead. It's much easier to maintain.

$VarNum[$j] = "yadda yadda yadda";

If for some reason you just can't do that (I can't imagine why, but who knows?), then you'd do something like:

${'VarNum'.$j} = "yadda yadda yadda";

This is perfect!
${'VarNum' . $j}
Thank you
