can "input" resolve a variable

[yusef88]

Code: Select all

  $a = "test";
  $s = input("", "",""); // input $a
  echo $s;

can the "input" command resolve the variable $a ?

[highend]

No, eval() is necessary for doing such a thing

Code: Select all

  $a = "test";
  $s = input("", "", '$a');
  echo eval($s);

Thanks for help

Code: Select all

echo get("shift")

is it possible to get control key also?

Shorter for eval($s) is *$s

But look out: in both cases $s should contain a valid variable name!

Edit: replaced must by should
