User-defined variable set

[therealwesfoster]

Here's what I'm trying to do.

 

<?php
$do = 100;

function setVar($var,$value)
{
  return eval("\$var = $value");
}

setVar("do",300);

echo $do; // I want it to echo 300. Instead of the original 100
?>

 

I'm not using the eval right I'm sure. So my question is, how would i be able to set a variable this way? I'm building a class and thats why I'm wanting a function like this.

 

Thanks

why do you have to use eval I believe you can use pas by reference in that case which is better

[therealwesfoster]

Well how would you do that?

 

This is something I've always wondered about
