PHP variable in session variable -

PHP variable in session variable -

i trying utilize session variable this:

$string = 'abc'; $_session[$string];

but access if utilize this:

$_session['abc'];

but error this:

notice: undefined index: abc

any ideas solve problem? :/

simply calling

$string = 'abc'; $_session[$string];

is not enough. it's becomes available when assign value it.

$string = 'abc'; $_session[$string] = 'test'; echo $_session['abc']; //test

also, create sure session_start() called on page you're accessing it.
