amazing variables -- brain teaser

[nearo]

I am relativly new to php and my ideas are getting ahead of my abilities. I am trying to get two variables to combine and become and entirely independent thrid variable.

This is what I have so far....

$plan_set_up_nearo = '0.00';

if ($bill_cycle == "1")

{
$base = '$plan_set_up_';
$combined = $base.$hosting_plan;
$set_up_fee = $combined;
echo "$combined";
} else {
echo "something else";
}

The variable $hosting_plan is sent to the above code with the value of nearo
My goal is for $combined to echo as 0.00, but
it outputs with the value $plan_set_up_nearo

I don't get it, any ideas?

sorry...

I want $set_up_fee to output the value of $plan_set_up_nearo, which was defined above as 0.00, so echo "$set_up_fee" shuld be 0.00. Not what I am getting which is $plan_set_up_nearo

i assume you're talking about variable variables.

http://www.php.net/manual/en/language.variables.variable.php

echo ${ $plan_set_up_ . $hosting_plan }

Thank you, your input got me on the right track, I don't think this is a variable.variable.... but this works

${'plan_set_up_'.$hosting_plan};

Thanks again

Your main problem in the original code is that you have used single quotes instead of double. Variable substitution will not be performed inside single quotes 🙂
