I don't understand what you are trying to do, but maybe you are trying to
achieve something like:
<?php
class Test {
var $var = '';
function Test() {
$this->var = "theVariableName"; // Hold variable name
$theVariableName = "whatever you want";
if (${$this->var} == $theVariableName)
echo ${$this->var}." is equal to ".$theVariableName;
else
echo "bad dog! stop it!";
}
}
new Test();
?>
