Actually, processing only stops at the first break statement, so in this
example, it would run through to case 3:
$var = 1;
switch($var)
{
case 1:
{
echo 1;
}
case 2:
{
echo 2;
}
case 3:
{
echo 3;
break;
}
case 4:
{
echo 4;
break;
}
default:
{
echo 'default';
}
}
This would display '123' in the output.
