simplest way to do with below code

$arr = array(
'key1'=>'value1',
'key2'=>'value2',
'key3'=>'value3'
);

$lastvalue = end($arr);
$lastkey = key($arr);

$arr1 = array($lastkey=>$lastvalue);

array_pop($arr);

$arr1 = array_merge($arr1,$arr);

OUTPUT

Array

    [key3] => value3
    [key1] => value1
    [key2] => value2
)
