Appending a value of a variable to a variable name?

I can’t figure out the syntax at all and have searched far and wide.

I would like to do this:

$uni = "ntu";
$selectedntu = "something";

echo $selected$uni;
// output should be the same as
echo $selectedntu;

In other words I’d like to use the contents of the second variable $uni to join onto the first variable’s name. $selectedntu has been set with a foreach loop, but I can’t figure out how to reference the two variables together in php.

Answer 1

Construct the string and use a variable variable $$

$uni = "ntu";
$selected = "something";

$new_variable = $selected . $uni; 
echo $$new_variable;

// Or..per your googleing..purely for reference for others later

$uni = "ntu";
$selected = "something";

echo ${$selected . $uni};
