How to convert string (name of a variable) to a variable in PHP? [duplicate]

Question

Is it somehow possible to use a string as an actual variable name? Sothing like this:

$a = '$myvariable[\'subitem\']';

How can I convert variable $a in order to actually work with a variable

$myvariable['subitem'] ?

EXAMPLE:

$myvariable['subitem'] = "hello";

$a = '$myvariable[\'subitem\']';

// do somenthing with $a

echo $a  // outputs "hello" instead of $myvariable['subitem']

You want the variable name to be the value of $myvariable['subitem']? — showdev

What's wrong with using $item = 'subitem'; $myarray[$item]? (The goal is unclear to me.) — user2864740

how about this:

$a = 'myvariable["subitem"]';
echo $$a;

Above is called variable variables

I think you dont get me right..

You mean $$a = "something new";

the $a is supposed to contain just a name of a varible..

I mean to use strings (that represent the names of variables) to get the actual variables..
