Dynamic Variable Name $$var

[Angelos]

Hello,

I need to dynamically specify the name of a variable. I just read that
$varA = "Cat";
echo $$varA;

OUTPUT: Cat

What I try to establish is somehow add a bit of text on my dynamic
variable name.
so:

$varA = "Cat";
$$varA.'Food' <------ I am not sure what should be the syntax in order
the variable name to be $CatFood

The reason I want to do that is because I take the first part of the
variable name from a Database.

Thanks.

I worked it out I think:

$a = "a";
$b = "b";
$varA = $a.$b;

$$varA = "jack";
echo "Dog name is: ".$ab;

You can also use the curly braces so you don't need to always assign a new
variable for that. Example:

$alpha = 'a';
$beta = 'b';
${$alpha.$beta} = 'all your phps are belong to us';
echo $ab;
