Sanjeev is right. You're thinking about the problem backwards.
You're
trying to build a Switch inside a loop. Remember, if you ever have
to do
some operating multiple times you're using a forloop, then the thing
that
you want to repeat(switch case) is INSIDE the for loop.
Not always true. Sometimes once you've made the switch it applies to
all
members of a data array. In which case switching on every iteration is
a
waste of processor since you can check a single time outside the loop.

You can run a switch inside a for loop and when a case is matched set a
variable to true.
the break statement will break out of the switch, then inside the
iteration code, after
the switch block, test the variable for true. If it is true the use
another break instruction.
That should break out of the loop altogether at the end on that
particular iteration.
like so:
for($i = 0; $i < somevalue; $i++)
{
$bar = false;
switch($anotherValue[$i]) // /this assumes you are looping
through an indexed array
{ case 'foo':
$bar = true
//other code;
break;
default;
// $bar is not set to true so the loop continues
}
if($bar == true)
{
break;
}
/* instead of the default line in the switch statement
else
{
continue;
}
*/
}
Hope this is useful.
