Changing Strings to Variables?

Daggeth

The title is confusing, I know but here is my problem, I need to convert a string into a variable name.. Ill give an example.

Variable1 = "hi";
Variable2 = "bob";

Now, I want PHP to take the value of Variable1 and set it as the name, than take the value of Variable2 and assign Variable1 its value.. so it would turn out like this:

$hi = "bob";

Does anyone understand the problem?

if you really have a string, look at this: http://www.php.net/manual/en/function.explode.php

you're looking for variable variables. Here's an example:

$Variable1 = "hi"; 
$Variable2 = "bob"; 

$$Variable1 = $Variable2;

Will basically create the following output

$hi = "bob";

I believe one of the most useful features of alot of languages is variable variables, which sometimes will confuse alot of people but once you get the hang of it, has to be one of the most useful features. 🙂 Also being able to use the value of a variable as a function call is very valuable in programming as well...

$myFunction();

the value of $myFunction(); will call that function.. sooo if $myFunction has the value of "addThis" then it would call addThis();

Just two of the most useful things 🙂

Just a philsophical difference, I'm not saying you're wrong. But IMHO variable variables make the code more complicated than it should be.

Most of the times I've seen people trying to use variable variables it was because they didn't understand how to use more powerful features of the language (usually associative arrays, but also references and objects are more appropriate).

What's wrong with this?

$myArray['hi'] = 'bob';
