Its not a good idea to do this what you want.
If you need something like that name may have different value against different reg, then you can use a 2D array as like:
store[name][reg] = new array();
Hope you analyses that and I redesign your code.

Although I would discourage doing anything like this in most circumstances, this is how you can do it:
<?php
$name = 'john';
$reg = 10;
${$name.$reg} = array();

"Although I would discourage doing anything like this in most circumstances" --- if you do, why not give a good advice?

Dear SO, I understand you all like reputation points, but STOP GIVING SILLY ADVICES. Thank you.

@zerkms To give proper advice on what to do instead of this construction, we'd have to know more about OP's situation. All we know is they want to concatenate 2 strings into a variable name.

OP asked, codefocus answered. OP did not ask if is this not a good idea, and has been offered warnings and alternatives... Can someone explain WHY this is not a good idea rather than ONLY giving advice other than what OP asked?
zerkms
@codefocus: right. That's why you need to ask OP about the real issue, not start answering blindly.

Ok then you can use it though it is not best practice.
<?php
// The very top of your php script
$vars = get_defined_vars();
// Now do your stuff
$name = 'john';
$reg = 10;
// Get all the variables defined in current scope
$john10 = array_diff(get_defined_vars(),$vars);
print_r($john10);
?>
$john[10] = ...anything wrong with using real arrays?
