Answer / sriram

Hey guys, what about swaping variables contains string
values? All of your solutions will suck... Try this and swap
any datatype without third variable... Happy Sensible Coding..

$v = 'sriram';
$u = 'lakshmi';

$v .= $u;
$u = substr($v,0,(strlen($v) - strlen($u)));
$v = substr($v,(strlen($v) - strlen($u)-1), strlen($v));

echo 'u = ' . $u .'<br>';
echo 'v = ' . $v;
