session variable in variable?

[galvin]

I have a session variable that will be set to a number called...

 

$_SESSION['number']

 

I have page where I want to set a variable in the format of $serv# (with "#" being the value of the session variable).

 

Is there a way to write one simple line of code that in effect says...

 

$serv . $_SESSION['number'] = "selected='selected'";

 

I'm just looking to avoid having to write this code...

if ($_SESSION['number'] == 1) {
$serv1 = "selected='selected'";
} elseif  ($_SESSION['number'] == 2) {
$serv2 = "selected='selected'";
} etc etc

 

It's basically putting a variable inside of a variable and I'm not sure if this is allowed/proper?

 

Any insight would be appreciated.

 

Thanks,

Gary

$serv1 =

$serv2 =

 

^^^ Don't use a series of numbered variables.

 

Use an array, then the $_SESSION['number'] variable can simply be used as the array index -

 

$serv[$_SESSION['number']] =

You want to use variable variables

<?php
${serv . $_SESSION['number']} = "selected='selected'";
?>

 

But a clear way of doing this would be to use a array:

<?php
$serv = array();
$serv[$_SESSION['number']] = "selected='selected'";
?>
