Variable Variables

[vanoosterhout]

I think that variable variable should somehow be able to solve my problem ... but I can not seem to make it work.

I have variables that end in a number. For instance:

$variable1
$variable2
$variable3

The variables are all named the same except for the number suffix. I am trying to find a way to define the number and call the variables using variables. I know this code will not work, but this hopefully illustrates what I am trying to do.

$variable3 = "I hope this displays";

$number = "3";
$displaythisvariable = "variable" . "$number";

echo "$displaythisvariable";

The output would hopefully be:

I hope this displays

Can anyone think of a way to do this?

<?php
$variable3 = "I hope this displays";
$number = 3;
$prefix = "variable";
$display = $prefix.$number;
$d = ${$display};
echo $d;
?>

Thanks a LOT.

The answer was so simple.

Thanks for showing me the light.

just curious:

could you also just do
$d = ${$prefix.$number};

?

Yeah, you could

The above was more of a breakdown to show him step by step whats happening
