You need to pass the level here:
<?php
for($i=0; $i<5; ++$i)
{ switch(1)
{ case 1:
continue 2;
}
echo "Not printable";
}
?>
This code won't output anything. Documented issue also.

The desired behavior is that continue is transparent to switch
statements - this behavior would mimic how if handles continue
statements.

The switch statement is a flow control construct - like for or if.
Because of this continue behaves within switch like it should in any
flow control contruct - it skips to the next loop of the construct.
However, switch does not loop - so continue behaves like break.
If you would like to use a continue embedded in a switch statement to
continue past a loop in an outside control construct, specify how many
levels you would like continue to break out of.
Try these examples to see what I mean:
<pre>
<?php
for ($i=0; $i<5; ++$i)
{
switch(1)
{
case 1:
continue 2;
break;
}
echo "Should be skipped";
}
// Should not output anything
for ($i=0; $i<5; ++$i)
{
for ($z=10; $z>5; --$z)
{
switch(1)
{
case 1:
continue 2;
break;
}
echo "\$z=$z\n";
}
echo "\$i=$i\n";
}
/*
Should output:
$i=0
$i=1
$i=2
$i=3
$i=4
*/
?>

in the script :
<?
for($i=0; $i<5; ++$i)
{ switch(1)
{ case 1:
continue;
}
echo "Not printable";
}
?>
the string is printed 5 times because the continue statement end the
switch (like break). In C and C++, and in the PHP manual the continue
(unlike break) isn't affected by surrounding switch statement and it
seems logical to me.
