Yes it refetches the variable passed to switch() to check whether it

the error message is on the closing '}' of the switch ...
does switch re-evaluate its argument on termination?
this is scary!

let the sample code say the problem
<?
error_reporting(E_ALL);
$str1 = '.........$...';
$str = &$str1;
$l = strlen($str);
for ($i = 0; $i < $l; $i ++)
{
switch ($str{$i})
{
case '$':
$str = '123'; // change string
$i = -1; // set to -1, for next loop to be 0
$l = strlen($str); // u know what this do
break;
default:
echo $str{$i};
}
}
?>
-----------
result:
-----------
.........
Notice: Uninitialized string offset: 9 in
d:\myfile\wwwroot\our-sky.com\test.php on line 19

$str = '123';
