PHP Swap (Simple Swapping)
- 3 Comment
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.

$a = ‘bar’;
$b = ‘foo’;$a = $a ^ $b;
$b = $a ^ $b;
$a = $a ^ $b;echo $a . $b;
// its faster and needs less memory ^^
