php how to generate dynamic list()?

Question

base on my understanding, this how list() work.

list($A1,$A2,$A3) = array($B1,B2,B3);

So with the help of list() we can assign val

Answer 1

This creates variables $A1, $A2, .... $AN for each element in your array:

$list =  array("a", "b", "c", "d");

extract(array_combine(array_map(function($i) {
        return "A" . $i;
    }, range(1, count($list))), $list));

echo implode(" ", array($A1, $A2, $A3, $A4)), PHP_EOL;

You can modify the name of the variables in the array_map callback. I hope I'll never see code like that in production ;)
