Appending a value of a variable to a variable name? [duplicate]

Answer 1

$_part$v;? maybe idk. I know you can do this:

$vname="variable";
$$vname="hello";
echo $variable;

//WOULD output "hello"

try this:

$name="_part";
$name=$name . $v;
$$name=$value;

Answer 2

You need variable variables:

echo ${'part_'.$v};
// or
$var = 'part_'.$v;
echo $$var;
