PHP Swap (Simple Swapping)

**

PHP Simple Swap >>

Hello programmers,

You know list function in php and array function. Just
type like below for swapping two variables $a and $b.

list($b,$a) = array($a,$b);

The above code is equivalent to:

$temp = $a;

$a = $b ;

$b= $temp;

Here we shorten the three line of code into a single line.
