Here i wan t to share about language variable variable. You can visit complate tutorial
here.
What does that mean $this->{$var}?
This is example how to use $this->4{$var}
$this->a = "hello";
$this->b = "hi";
$this->val = "howdy";
$val = "a";
echo $this->{$val}; // outputs "hello"
$val = "b";
echo $this->{$val}; // outputs "hi"
echo $this->val; // outputs "howdy"
echo $this->{"val"}; // also outputs "howdy"

This of course is working within a class context. You can use variable variables in a local context just as easily like this:
$a = "hello";
$b = "hi";
$val = "a";
echo $$val; // outputs "hello"
$val = "b";
echo $$val; // outputs "hi"
