note 43995 added to language.variables

I was bored (nothing new :)) so I tried to code few extraodinary lines and somehow come with something I could not explain at first. Here is the code: <?php $x= 'a'; $$x= 'b'; echo $x . "\n"; echo $a . "\n"; echo $$x . "\n"; $x= $$x ; echo $x . "\n"; echo $a . "\n"; echo $$x . "\n"; ?> With out running the code can you predict what the output would be? Careful now! ----------------------------------------------------------- The explanation: $x= $$x // $x now points to the value b The last line takes the value of $x which is 'b' and creates a variable variable $b which is NULL. Try adding this line of code before the last line: $b= 'Ah ha!'; and run the code again.
